Question

If the angles of a triangle are in the ratio 1:2:2,then it is a    ..........triangle​

Answer 1

Answer:

Isosceles triangle...

Answer 2

Answer:

The angles are 36, 72, 72

Step-by-step explanation:

let us take x as common

1x + 2x + 2x = 180

5x = 180

x = 180/5

x = 36

now

1st angle 1x = 1 * 36 = 36

2nd angle 2x = 2* 36 = 72

3rd angle 2x = 2* 36 = 72
