Question

in triangle abc .angle a=30°,angle b=60° find the measure of angle c​

Answer 1

Angle c is 90 °.....

Answer 2

Given :

In triangle ABC, ∠A=30° and ∠B=60°

To Find :

The measure of ∠C

Solution :

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.

So in Δ ABC,

               ∠A + ∠B + ∠C          =  180°

putting the value ∠A = 30° and ∠B = 60°,

            30°  +  60° + ∠C          =  180°

⇒                              ∠C           = 180° - 90°

∴                               ∠C           = 90°

∴ The measure of angle C of the triangle ABC is 90°.
