Q
R find x plz ​

Answer 1

HOW TO SOLVE?

Angle P = Angle R = x

(Because angle opposite to equal sides are equal)

Angle Q = 90°

90° + x + x = 180°(angle sum property of a triangle)

90° + 2x = 180°

2x = 180° - 90°

2x = 90°

x = 90°/2

x = 45°

FINDING Y:

x + y = 180° (Linear pair angle)

Put the value of x.

45° + y = 180°

y = 180° - 45°

y = 135°
