Question

In triangle PQR ,angle p=50 ,angle Q=60 then angle R=?​

Answer 1

Answer:

Using angle sum property of triangle

∠P+∠Q+∠R=180 ∘

⇒60 ∘ +50 ∘+∠R=180 ∘

⇒∠R=180 ∘−110 ∘

=70 ∘

So ∠R is the largest angle and side opposite to largest angle is the longest side.

∴PQ is the longest side.

Answer 2

Answer:

angle R = 70 degree ..

Explanation

as the triangle the property of triangle suggest, tht sum of all angles of a triangle is 180 degree . so

50 + 60 + x = 180

110 +x = 180

x = 180 - 110

ie , x = 70 degree Answer
