Question: Two angles in a triangle are 30 degrees and 60 degrees what is another angle ?

----------------------

Answer.

In this triangle lets consider the angles as A, B and C, where the angle C has to be found.

We know that,

Sum of all three angles of an triangle = 180°

We use this formula to find out the third angle.

Given that,

∠A = 30°

∠B = 60°

To find

Value of ∠C

Solution

∠A + ∠B + ∠C = 180° (ASP of a Triangle)

30° + 60° + ∠C = 180°

90° + ∠C = 180°

∠C = 180° - 90°

∠C = 90°
