. 5) sin u = 0.7071
Sec u= 1/cos u
Cos u=1/sec u
Cos u= 1/1.414
Cos u=0.7071
u = cos`(0.7071)
u=45
Sin u= sin 45 = 0.7071 or 1/root 2
3) 240 pupils.
Average means mean for set of data or age of. students
Mean=sum of students age/number of student
Let "x" be the d sum of student age for 120 new
Students while we no the mean is 32
x/120=32
x=3840
So for the old students let there sum b "y" and
There number b "z" while we no there mean is
40
y/z=40
y=40z
When the new mean was calculated its equal to. the old
Mean reduced by 4 dat
40-4=36
New mean=sum of all students/no of all student
Note all students means every student both old and new
36=x+y/(120+z)
36=3840+40z/120+z
36(120+z)=3840+40z
4320+36z=3840+40z
4320-3840=40z-36z
480=4z
z=120
Total number of students=no of all student
120+z=120+120=240.

i misplaced my fone dats y, and there are many unilag grup sum1 dnt knw where 2 log on to.
abeg aid me in solving dis 4 questns.
1. A boy thinks of a number. He squares it and subtracts from it original number. The result is 42. what is the number?
2. The altitude of a triangle is 2cm less than the base and the area is 262.5cm2. Find the length of the base.
3. A pupil multiples 3 numbers. One of them is the number 4. of the other 2 numbers, one is reater than the other by 6. if the result of the multiplication is 45, find the unknown numbers.
4. A rectangle has a perimeter of 54cm and an area of 180cm2. Find its length and width.

Umartins help me solve this, 1. The line 3y-x=7 makes an angle of tita with the positive x-axis. The value of sin tita is? 2. A boy received a cash gift from his parents on his 10th birthday. On each succeeding birthday, he received twice the amount received in the previous year. If he had received a total of 31,500 by the time he was 15, the cash gift for his 12th birthday was?

since they are on different longitude, you have to add;
8^o + 18^o
= 26^o
Remember; 1^o = 4mins
4 * 26 = 104mins.
