Question

in a right triangle, the acute angles are in the ratio of 4:5. Find the acute anges of the
triangle​

Answer 1

Answer:

let the angles be 4x and 5x.

4x +5x+90=180

9x=90

x=10

now one angle is 4×10=40

and other is 5×10=50

Answer 2

Step-by-step explanation:

Let x be the common factor .

The first angle is 4x and the second angle is 5x.

By the angle sum property of a triangle.

4x+5x+90=180

9x+90=180

9(x+10)=180

x+10=180/9

x=20-10

x=10

Thus first angle will be

4x=10×4

=40

the second angle will be

5x=10×5

=50
