Question

please answer it correctly in a paper and show please so I can understand easily​

Answer 1

Step-by-step explanation:

let the 3 angles are 1x, 2x, 3x

now

x+2x+x = 180

4x = 180

x = 180/4

x = 45

the angles are 45, 45, 90

Answer 2

Answer:

The three angles are 45°, 90°, 45°

Step-by-step explanation:

Sum of the ratios = 1+2+1 = 4

(angles of a triangle sum up to 180°)

1st angle = 1/4*180 = 45°

2nd angle = 2/4*180 = 90°

3rd angle = 1/4*180 = 45°
