Answer 2

Answer:

Since , both triangles are similar , then each angle of triangle is equal to the each angle of another triangle.

In ∆PQR ,

angle A = angle P = 53°

angle Q = 77°

angle R = x

Since , sum of angles in a triangle = 180°

=> angle P + angle Q + angle R = 180°

=> 53° + 77° + x = 180°

=> 130° + x = 180°

=> x = 180° - 130°

=> x = 50°

Angle R = 50°.
