Question

. If ∆ABC≅ ∆RQP, then the value of x is * Captionless Image (a) 25 (b) 50 (c) 75 (d) 90

Answer 1

Answer:

If two triangles are equal then their corresponding angle are also equal

∴∠A=∠R,∠B=∠Q and∠C=∠P

In △ABC

∠A+∠B+∠C=180

∘

80

∘

+60

∘

+∠C=180

∘

∠C=180

∘

−140

∘

=40

∘

∴∠P=40
