Question

In ∆RST , ∠R = 60⁰,∠S = 75⁰,∠T= 45⁰ Find the greatest and smallest side of ∆RST.​

Answer 1

Step-by-step explanation:

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.
