Question

3) Find the values of the unknown x and y in the following diagram.
​

Answer 1

$\huge\colorbox{green}{Answer}$

Value of y = 180-50+60

= 180- 110

= 70°

Value of x = 180 - 70

= 110°

Answer 2

x=60+50( exterior angle= sum of two opposite interior angles)

x=110

x+y=180(sum of angles on a straight line)

y=180-x=180-110

y=70
