Question

find the measure of x and y in the following fig ​

Answer 1

in ∆ PQR by angle sum property

x +70+45=180

x + 115=180

x=180-115

x = 65

y = x + 70(exterior angle property of triangle

y=65+70

y=135

please follow me

Answer 2

Answer:

In ∆ PQR

x + 70° + 45° = 180° ( Angle sum Property of a Triangle)

x + 115° = 180°

x = 180° - 115°

x = 65°

then Y = x + 70° ( Exterior Property of ∆)

Y = 65° + 70°

Y = 135°

I hope you understand.

Thanks for asking.
