Value of <R. Justify your answer.
your answer​

Answer 1

70,A=P=70,B=Q=40,C=R=180-70-40=70

Answer 2

Answer:

Step-by-step explanation:

GIVEN

ΔABC ~ ΔPQR

∠B= 40°

∠P=70°

SINCE THESE TRIANGLES ARE SIMILIAR

∠B= 40° = ∠Q

∠P=70° = ∠A

THEREFORE IN ΔPQR

∠P=70°   GIVEN

∠Q= 40°

THEREFORE BY ANGLE SUM PROPERTY

∠P + ∠Q + ∠R = 180

70° +  40 °+ ∠R = 180

∠R =  180° - 110°

∠R =  70°
