Question

if one angle of a triangle is 90 degree and other two angles are in ratio 1 ratio 2 find the angles

Answer 1

Let the two angles be 1x and 2x
90 + 1x + 2x = 180
3x = 90
X = 30

Answer 2

Let the first angle=x

Second angle=2x

A/q,

x+2x+90°=180°

3x+90°=180°

3x=180°-90°

x=90°/3

x=30°

Then first angle=x=30°

And second angle=2x=2×30°=60°
