Question

in right angled triangle , one acute angle is 30 degrees find the other acute angle

Answer 1

30+x = 90
x = 90-30
x= 60
acute angle = 60

Answer 2

First angle = 30°

Second angle = 90°

Let the other acute angle be a

By angle sum property of triangle,

Sum of three angles = 180°

=> 90 + 30 + a = 180°

=> a + 120° = 180°

=> a = 60°

Other acute angle = 60°
