Question

Find the value of x and y in each of these figures

Answer 1

Answer:

135° = 85° + x ( exterior angle property )

135 -85 = x

x = 50 °

now by angle sum property

85 + 50 + y = 180 ( vertically opp. angle)

y = 180 - 135

y = 45°

Answer 2

Step-by-step explanation:

In the figure,

let's the remaining angel be z°

z°+135°=180° (linear pair)

z = 180-135

z= 45°

z=y. (vertical opposite angle)

y = 45°

now ,

in the triangle

85°+x+z = 180

85+x+45 = 180

x = 180-130

x = 50
