Question

In a right angled triangle, the acute angles are in the ratio 4:5 . Find the angles of the triangle in degree and radian.​

Answer 1

Answer:

the angles are 90 4x and 5x

4x+5x+90= 180(angles in a triangle are 180 degrees)

9x+90=180

9x=90

x=90/9=10

4x= 4x10=40

5x= 5x10=50

Answer 2

Answer:

90 degree 40 degree and 50 degree

Step-by-step explanation:

let reqd angles = 4x and 5x

a/q to angle sum property of a triangle

90 degree + 4x +5x=180

9x=180-90

x=90/9

x=10

reqd angles=4*10=40 degree and

                   =5*10=50 degree
