Answer 2

Answer:

the right answer is 1 x is equal to 45° to x is equals to 90° and one x is equals to 45°

Step-by-step explanation:

let all the angles =1x,2x,1x

we know that the sum of all sides of a triangle is 180°

so the equation becomes

1x+2x+1x=180°

4x=180°

x=45°

so from here we get 1X=45°

2x=2*45°=90°

1x=45°
