Find the unknown side length, x. Write your answer in simplest radical form.

Answer:
The length of he hypotenuse of the triangle is x = 65.
Step-by-step explanation:
Here, the base of the right triangle = 56
The perpendicular = 33
The hypotenuse of the triangle = x
Now, by PYTHAGORAS THEOREM: In a right angled triangle
[tex](Base)^{2} + (Perpendicular)^{2} = (Hypotenuse)^{2}[/tex]
or, here
[tex](56)^{2} + (33)^{2} = (x)^{2}[/tex]
or, [tex]x^{2} = 3136 + 1089 \implies x = \sqrt{4225} \\x = 65[/tex]
Hence, the length of he hypotenuse of the triangle is 65.
