Question

find the values of x and y in the following figures​

Answer 1

Answer:

sum of angle of triangle is 180 so it is a right angle triangle and 30+90+x=180 then x=60,and linear pairso 30+y=180 , y= 150

Answer 2

Answer:

y + 30° = 180° { Linear pair }

y = 180° - 30°

= 150°

x + 30° + 90° = 180°

{ Angle Sum Property }

x + 120° = 180°

x = 180° - 120°

= 60 °

So , x = 60° and y = 150°
