The hypotenuse of the right triangle measures 3 units.
<h3>
How to find the hypotenuse?</h3>
Here we know that both legs measure:

If we use the Pythagorean theorem, we will see that the hypotenuse H can be written as:

Then we conclude that the hypotenuse of the right triangle measures 9 units.

The answer is9 you just subtract
Metathod 1
4/5=27/x
mutiply 4/5 by 27/27 and multily 27/x by 4/4
108/135=108/4x
therefor
108:135=108:4x
therefor
135=4x
divide by 4
33.75=x
metahod 2
4/5=27/x
multiply oht sides by x
4/5x=27
multiply both sides by 5/4 to clear fraction
x=135/4
x=33.75
