all this indomie children can abuse their elders

TSRC:
Wrong.
Nnadozie was responsible for saving a lot of korean assault.

Go and check the stats again. The koreans played better, had more shots on target, had more possession and pressured our goal endlessly.
I can't count how many times our keeper was put under pressure which she along with the defence dealt with very well.
If oshoala was as effective as our goal keeper yesterday, Nigeria would have scored five.

n.a. wah dis guy needs brain checker

This your likes go soon turn to dislikes very soon. Guardiola had long earned his stripes as an assistant coach, and also coached a Barcelona junior team(can't remember which one). I'm sure Zidane even had more experience when he took charge of Real than Lampard has now. Chelsea are just getting way in over their heads if I must say. It ain't gonna end well believe me

cheezy4real:
Chelsea's champions league was gotten by Di Mateo, an inexperienced coach. Let dem gamble

prodigyhenry:
Sarri was trophyless before he joined Chelsea. Zidane hadn't coached a top division team before a whole real Madrid made him head coach. Guardiola had no experience when he became Barca's most successful coach ever. So it's not about experience if you've got it, you've got it

Even the dstv southafrican crew gave it to nnadozie.

Bigot.

Mrshape:
I have been fetching them out lately with my post sir,
It gives me joy to see like minds sir.

Mrshape:
Good one sir √√√√√√√√√√√(11/10)

moniniola:
Jeez! do questions like this still exist?somebody like me will drive my children early to school so they can copy maths assignment lol...I hate that subject

Mrshape:
yes I observed that but I gave him credit for the first attempt on point.

Mrshape:
If the students have done technical drawing, the will be able to easily understood the concept sir.
If the haven't they can still understand with a good 3D diagram in the blackboard and explanation,
Were resources limit most is teaching Longitude and Latitude without a globe,

Mrshape:
Yes you and abeos gave the correct 2D representation, while Razor017 gave the correct 3D in his last diagram.

Rezos017:
At natural waves:
I was trying to correct a wrong idea u had: the tower is north of D, meaning directly in front of D. But its not the whole tower that is at an angle of elevation of 35degrees from D. Its just the top of the tower, ie point B. Its clearly detailed in the second diagram. You seem good at basic maths. You can see the difference

Mrshape:
You call it straight forward because you already understood the ideal,
If I tell you the number of students and maths teachers around the word that have failed this particular question you will not believe, when I presented the solution, the only way the comprehend is when it was in 3d dimension,
Students will not be ask to draw 3D, but only does that understand 3D formation of it can translate it to what u did their.
Note my diagram is same as, @Razor017 diagram.

Mrshape:
U did a great job, but a good 3D diagram will be better understood.

castro316:
So why were you so quick to say my drawing when your aptitude reasoning is high. This is the statement my teachers used to punish me that year which I found out was very bad thing to say In an academyof "learning"

Rezos017:
It isn't merely one point that is due East of another(read the question again).

Rezos017:
It is the tower that is due east of point C, ie on the right side of C.

Rezos017:
The angle of elevation of the top of the tower B from point D is 35 degrees

Rezos017:
I have pointed out that little mistake in d diagram. I"l post another one to show the correction. From the perspective of the diagram, points C and D as well as the tower itself are all on the same horizontal ground.

Rezos017:
Just a little rotation.

castro316:
The problem is understanding english language (statement problems) not the mathematics. The question says C and D are different observation points at the foot of a tower A Ie the same plane. From there start making your analysis. And before you start your insults, (which I will not indulge you) why did you come out to say my diagram is wrong without checking your facts? However draw yours. If you came to learn stop being a spectator. I am not C. Ronaldo or Messi. Biko. I am SS3 teacher and I know what I drew there

Rezos017:

SOLUTION

Question says;
C and D are observational posts on the same horizontal ground at the foot A of a vertical tower AB. The tower is 18m due North of D and 24m due East of C

Question should be
C and D are observational posts on the same horizontal ground AS the foot A of a vertical tower AB. The tower is 18m due North of D and 24m due East of C
After correcting the grammar, this is how it should be solved.

STEP 1

Mark a dotted point as the point D and trace it up to another dotted point. The second dotted point represents the tower. This should be a straight line. why? Because the question says the tower is 18m due North of D. So, label the line as 18m


STEP 2

From that second dotted point which represents the tower, draw another straight, dotted lines to the left and put a dot at the end to represent C. Label it as 24m. Why? The question says that, the tower is 24m due East of C


STEP 3
From the question , we know that points C and D are on the same horizontal ground. So, draw a straight line to join points C and D


STEP 4
Draw a straight line to join the line /CD/ from our initially dotted point that represents the tower. THAT STRAIGHT LINE YOU HAVE JUST DRAWN IS THE TOWER AB


STEP 5

We know from the question that the foot of the tower is A and the top is B. So, label the bottom that is now on the same line as /CD/ as A and label the top as B. You will then observe that the diagram is in line with the question as C,A and D are all on the same line.

I will attach the necessary pictures when I get on a phone I can snap with or when I can sketch. I am on the laptop now.
I hope this helps someone.

Abeos:
My bad . Although how will that due north be placed then cos it's a bit ambiguous

castro316:
mr man that diagram is in 3D. Try drawing a cube and make the bottom surface stay on the same level on your paper. Then tell me your waec grade after

Mrshape:
Some one draw my attention to a problem recently that he think is incorrect, he have search the Internet with many website have the question but no diagram or solution to it,
But behold the problem is correct, and easy, but I found out another problem of our students, which was also pronounced in the just concluded WASSCE mathematics question, I will reveal the problem I found out about our students later,
Let someone attempt this first

castro316:
Is this what you are looking for?

Rezos017:
Most bright students, even a huge percent of maths teachers, would still struggle to come up with a diagram that captures this question. Its not the solution that's difficult; its the diagram. Most times, students are taught only two dimensional bearing problems, but three dimensional problems like the one in the post are completely ignored.
