Which equation can be used to find x, the length of the hypotenuse of the right triangle? A triangle has side lengths 63, 16, x. 16 + 63 = x 16 squared + 63 = x (16 + 63) squared = x squared 16 squared + 63 squared = x squared

16 squared + 63 squared = x squared

Explanation:

Hi, since we have a right triangle we have to apply the Pythagorean Theorem:  

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.  

Replacing with the values given:  

x^2 = 63^2 + 16^2  

So, the correct option is  

16 squared + 63 squared = x squared
