What is the value of x. enter your answer in the box. a triangle with 3 sides that's a right triangle the longest one is 24 then 7 then x. what is x x=

Use the Pythagorean Theorem: a² + b² = c².
a and b are the legs, c is the hypotenuse.

Refer to the picture :) I just drew a standard right triangle, *not to scale*.
The hypotenuse is always the longest side of a right triangle, so I plugged in 24 for c. I plugged in x and 7 for a and b.

x² + 7² = 24²
Square 7 and 24.

x² + 49 = 576
Subtract 49 from both sides.

x² = 527
Square root both sides to isolate and find x.

x = 23
