Question

IF TRIANGLE ABC ~= TRIANGLE PQR AND ANGLE A = 65°, angle B =45° then angle R is

Answer 1

Answer:70°

Step-by-step explanation:

Given,Δ ABC≅ Δ PQR  

therefore, ∠A=∠P=65°

                 ∠B=∠Q=45°

                  ∠C=∠R=?

In ΔABC,

∠A+∠B+∠C=180°(Angle Sum Property of Triangle)

65°+45°+∠C=180°

      110°+∠C=180°

              ∠C=180°-110°

               ∠C=70°

Since ∠C=∠R

          ∠R=70°
