Answer 1

Step-by-step explanation:

let ratio be 1x:2x:1x

1x+2x+1x=180°

4x=180°

x=180°/4

x=45°

hence,middle angle =2x=90°

Answer 2

Answer:

let those three angles be 1x, 2x, 1x then according to the angle sum property of

a triangle

x + 2x + x = 180°

4x = 180°

x = 180°-4

45°

so the angles are 45°, 45°, 2x45°= 90°
