Question

If ∆ABC ~ ∆PQR, m<A = 40°, m<B = 35° then m<R = ?​

Answer 1

Answer:

Correct option is

B

AB

Using angle sum property of triangle

∠A+∠B+∠C=180

∘

⇒35

∘

+65

∘

+∠C=180

∘

⇒∠C=180

∘

−100

∘

=80

∘

Side opposite to largest angle is the longest side of any triangle.

Here ∠C is the largest angle and side opposite to it is AB

So AB is the longest side.

Answer 2

Step-by-step explanation:

it is so simple.

ABC congruent to PQR

therefore,

angle A = angle P = 50 degrees

angle B = angle Q = 60 degrees

angel C = angle R = 70 degrees

A+B+C = 180

50 +60 + C = 180

110 + C = 180

C = 70

by angle sum property of .

hence angle R = 70 degrees
