Answer:

the girls be 12 and boys be 48 respectively

Step-by-step explanation:

The computation of the number of boys and number of girls is shown below:

Let us assume A be girls

And, b  be boys

According to the question

b = 4 × a

b - 8 = 2 × (a + 8)

b - 8 = 2 × a + 16

4 × a -8 = 2 × a + 16

4 × a  - 2 × a = 16 + 8

2 × a = 24

a = 12

Now

b = 4 × a

= 4 × 12

= 48

Hence, the girls be 12 and boys be 48 respectively

Answer:

FE = 30°

Step-by-step explanation:

arc FGC = arc FG + arc GB + arc BC

220° = 90° + arc GB + 70° . . substitute known values

60° = arc GB . . . . . . . . . . . . . subtract 160°

__

External angle A is half the difference of arcs EG and GB:

30° = (1/2)(arc FE +90° -60°) . . . substitute known values

60° = arc FE + 30° . . . . . . . . . . . multiply by 2 and simplify

30° = arc FE . . . . . . subtract 30°

_____

The key to this problem is the relationship between external angle A and the measures of the arcs it subtends.
