Question

In two triangles,ABC and PQR angle A
=30, angle B = 70,angle P=70,angle Q = 80 and AB = RP, then ​

Answer 1

Answer:

Then angle R is 30°.

Step-by-step explanation:

And the

Triangle ABC~ to TRIANGLE RPQ

Answer 2

ΔABC  ≅ ΔRPQ

Step-by-step explanation:

in  Δ ABC

∠A = 30°

∠B = 70°

∠A + ∠B + ∠C  = 180°

=> 30° + 70° + ∠C = 180°

=> ∠C = 80°

in  Δ PQR

∠P = 70°

∠Q = 80°

∠P + ∠Q  + ∠R  = 180°

=> 70° + 80° + ∠R = 180°

=> ∠R = 30°

∠A =  ∠R = 30°

∠B =  ∠P = 70°

∠C = ∠Q = 80°

=> ΔABC  ≈ ΔRPQ

AB = RP

=> ΔABC  ≅ ΔRPQ
