Question

Calculate the values

Answer 1

a=108;b=36;c=72

Explanation:

Answer 2

a = 108°

b = 36°

c = 72°

Explanation:

Note : the sum of the interior angles of a regular pentagon = 540°

Then

The measure of one interior angle of a reg pentagon =540/5 = 108°

Therefore a = 108°

c = 180 - 108 = 72°

SRT is a new isosceles triangle then :

`b=(180-108)/(2) = (72)/(2) =36`
