Question

in triangle ABC,. A.30 , B.60, find C​

Answer 1

We are provided that :-

∠A = 30°

∠B = 60 °

Then as from angle sum property of a triangle :-

Sum of all three angles is equal to 180°

Then

∠A + ∠B + ∠C = 180°

→30° + 60° + ∠C = 180°

→ 90° + ∠C = 180°

→ ∠C = 180° - 90°

→ ∠C = 90°

Answer 2

Answer:

A = 30 , B = 60, let C = x

we known that sum of the angles of triangle = 180

therefore, A+B+C = 180

= 30+60+x = 180

= 90+x = 180

= x = 180-90

= x = 90

therefore C = 90
