Answer:
x = 18
Step-by-step explanation:
The Pythagorean Theorem, a2 + b2 = c2, a2 + b 2 = c 2 , is used to find the length of any side of a right triangle.
In a right triangle, one of the angles has a value of 90 degrees.
The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.
