Question

In a right angled triangle, two acute angles are in the ratio 2:3, what are their measures?

Answer 1

Let the two acute angles be 2x, 3x

2x + 3x = 90
5x = 90
x = 18
First angle = 2x = 36
Second angle = 3x = 54

Answer 2

wait a min guys
let the angels are ......
Let the first one be equal to 2x and the second one be 3x. The sum of 2x and 3x is 90degree.
2x + 3x = 90degree
(2 + 3)x = 90degree
5x = 90degree
x = 90degree/5
x = 18degree

The first angle is 90degree
The second one is 2x or 2 x 18 =36.
The third one is 3x or 3 x 18=54.
