The acute angles of a right triangle are in the ratio 2 : 1. Find each of these angles.​

Answer»

Answer:

so if the TRIANGLE is right angles so one angle=90°

let x be the constant of PROPORTIONALITY so 2= 2x and 1= x

now, 90°+2x+x= 180°(sum of angles of a triangle)

90°+3x=180°

3x=180°-90°

3x=90°

x=90°/3

x=30°

∴1x= 1×30°= 30° and 2x=2×30°=60°
