angle subtended at the center (the obtuse angle) = twice angle subtended at the circumference

femi4:
Lets go

k²=30² + 14² - 2*30*14 cos a

k² = 1096 - 840 cos a

But 180 + 2b =2a

a = b+90°

Hence k² =1096 - 840 (cosb cos90 - sinb sin90)

K² = 1096 + 840 sinb


And sin b =30/2r

k² = 1096 + 840 *30/2r
= 1096 + 12600/r

Also 4r² = k² + 900

4r² - 900 = 1096 + 12600/r

4r³ -1996r - 12600 = 0

r³ - 499r - 3150 = 0

r = 25, -7 or - 18

R = 25 (The positive value)

LAST SHAPE FOR TODAY

Find the area of the polygon,
Or tell us the regularity your observe.

ifada123:
Check it out
I skiped some simplification though

ifada123:
It works that way
As far the lenghts are same and it is also inscrbed in same circle the polygon is same,

Solid foods belongs to matured people, at this time everyone know what eight sided polygon is called, but what, how do we interact with an irregular polygon I believe it is a problem to many,
Show your workings
What is the area of the eight sided polygon?

ifada123:
If you have any objection or questions to my workings you can please express yourself let's clear the doubt.

Mrshape:
It is obvious a lot of people don't really understand how polygon operate must especially when dealing with irregular polygon, thus I made another shape on polygon
Find the area of the octagon,
Let the solving begin,
We are here to learn.
I remain Mr Shape

No hukus packus pls.

Answer is 7
Since the chords are enclosed to form a cyclic polygon and are of lengths 1,2,3,5,7,11,13
Angle at center =360
Ratio of angles =1:2:3:5:7:11:13
Sum of ratio =42
Working with chord 7
Angle subtended by chord 7 =7/42 *360
ANGLE = 60
Length of chord =2rsin®/2
7=2rsin30
R=7/2sin30
R=7

Mrshape:
Let the anglees subtended at the center of each sector

by the perpendicular line draw from the circle centre

@1,@2,@3,@4,@5,@6

@1+@2+@3+@4+@5+@6=180

Sin^-1(1/R) +sin^-1(1.5/R)+sin^-1(2.5/R)+sin^-1 (3.5/R)

+sin^-1 (5.5/R)+sin^-1 (6.5/R)=180

The substitute values into R to check which is the

closest to 180° note you should start from values grater

than 6.5 because height of the longest chord

h=√(R^2-6.5^2)

Note walfrom aphal can't even compute that and get

numerical values, so only substitution works or graph it

Thus R =7.4233units.
Look forward to my next shape, I remain Mr shape your shape lover,

CuteRedd:
what school? And what was the reason given for loan rejection?

GTR1:
I know of people who got around this time... can you be more specific on the rejection? What stage were you and what reason did they provide. By the way, prodigy isn't running out of funds, infact they need more applicants because it is a very lucrative business to them.

jimohibrahim:
Now I regret cashing out 22k from a 258k ticket cos of impatience now the ticket don enter, I cant stop thinking about it...I'm sad

Jiddyplus:
Please can anyone assist in resizing my image to fit the requirement.

KODACK:
Did you see optional there...... Nawa.

In Nigeria, everything is compulsory.


I just finished registration for someone......guess what.....the reg. Number is over 450k .

Only God knows what the number will reach after two weeks

theoptimist298:
Did you crop before resizing to 600 by 600 or u cropped after resizing

Swargu:
Please clear cache..
But before you log out place your hand on the part of the screen that contains bio data which is the first menu...
After clearing cache once you try to login again and it says login in
Start clicking that part of the screen where you placed your hand, click like there's no tomorrow, most especially if you added professional cert and it's not necessary to you please jejely remove it..
For the passport aspect, as soon as I cropped from directly above my head to directly below my jaw it worked. I was even shocked.

Pictures size 200kb below, 600x600 px, crop directly above your head to directly below your jaw.. That's what worked for me, good morning

Uzee24:
Lolz..its always like this bro... once info like this comes out, millions of people jump on the site at the same time and the server is bound to have some issues handling the traffic. Same happened to N-power, infact npower even crashed.

I suggest U give it time, try in the night too, U just might be successful. I signed up with 3 different email accounts before I could succeed.

Hiploko:
Site is very very OK now!!!

This NNPC career portal is scrap. It was poorly built. I give the developers that did this 1/10. There is serious incompetence in that organisation. The job application appears as if one is climbing a mountain. Nonesense!
