Question

In triangle pqr, angle p=50 degree and angle q=60degree, then which is the longest side

Answer 1

In Δ PQR

∠P=50°

∠Q=60°

∠P+∠Q+∠R=180°    (By angle sum property of a Δ)

50°+60°+∠R=180

110°+∠R=180°

∠R=70°

In ΔPQR ∠R is largest angle

∴PQ is also largest side(In Δ, side opposite to the greater angle is larger)

Answer 2

Answer:

if angle P is equal to 50 degree Q is equal to 60 degree and R is equal to 70 degree then the largest side of triangle pqr is p r because largest side of triangle is equal to largest angle so angle R is largest angle and opposite side is p r then PR is also a largest side of triangle pqr
