Question

Calculate the values

Answer 1

Answer:

a = 108°

b = 36°

c = 72°

Step-by-step 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 :

$b=\frac{180-108}{2} = \frac{72}{2} =36$

Answer 2

Answer:

a=108;b=36;c=72
