Question

solve this I will give like​

Answer 1

Answer:

option (a) is the right answer

Step-by-step explanation:

if ∆ABC~∆ PQR

therefore ,Angle A =Angle P

Angle B= Angle Q

Angle C= Angle R

Since,if Angle B =70°= Angle P

In ∆ABC

AngleA+AngleB+AngleC=180°

70°+50°+AngleC=180°

AngleC=50°

Hence,AngleR=50°
