Question

1. Two angles of a triangle are 30° and 80°. Find the third angle​

Answer 1

Step-by-step explanation:

The sum of all three angles in a triangle = 180°

given two angles 30° and 80°

let the third angle be 'x'

30 + 80 + x = 180

110 + x = 180

x = 180 - 110

x = 70

hence the third angle is 70°

Answer 2

Hello guys.

As we know that sum of all angles of triangle = 180°

So let third angle be x

so, x + 30° + 80 °= 180°

x= 180 ° - 110°

x = 70°
