The acute angles of a right angle triangle are in the ratio 4:5,then find the acute angle.

they add to 90 degrees, so

4x+5x = 90

find x, and then the angles are 4x and 5x

I think x value 10

that is correct.

4x+5x+90=180

9x=90
X=10
1) 4×40
2) 5×50

To find the acute angles of a right triangle, knowing that they are in the ratio 4:5, we need to use some trigonometric ratios.

Let's assume that the acute angles of the right triangle are 4x and 5x. Here, x is a constant.

Since we know that the sum of all the angles in a triangle is 180 degrees, we can write the equation:

4x + 5x + 90 = 180

Combining like terms, we have:

9x + 90 = 180

Subtracting 90 from both sides, we get:

9x = 90

Dividing both sides by 9, we get:

x = 10

So, one angle is 4x = 4 * 10 = 40 degrees, and the other angle is 5x = 5 * 10 = 50 degrees.

Therefore, in the given right triangle, the acute angles are 40 degrees and 50 degrees.
