Question

What is the value of y?

Answer 1

the sum of triangle is 180 :

`y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 75 \\ 2y = 108 \\ y = (108)/(2) \\ y = 54`

Answer 2

QUESTION:- What is the value of y?

ANSWER:-

SUM OF ALL INTERIOR ANGLE = 180

`y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 72 \\ 2y = 108 \\ y = (108)/(2) \\ y = \frac{ \cancel{108}^{ \: \: \: \tiny{54}} }{ \cancel{2}} \\ y = 54 \degree`
