Answer 1

Sum of all angles of a triangle = 180°

Let the third angle be x.

So, 18.6° + 113.4° + x = 180°

=> 132° + x = 180°

=> x = 180° - 132°

=> x = 48°

So, the third angle is 48°.

Answer 2

3rd Δ = 48°

Step-by-step explanation:

sum of all Δangle of a triangle = 180°

so, let 3rd angle be x

18.6° + 113.4° + x = 180°

132° + x = 180°

x = 180° - 132°

x = 48°
