Find a third number so that numbers form a right triangle 13,85

The third number is 84

Step-by-step explanation:

Given two numbers as 13 , 85

To make the triangle to be right angle , Pythagoras theorem is applied ,

i.e H² = P² + B²

    Here H = 85 ,

    Let perpendicular = x and base = 13

So, P² = H² - B²

Or,  x² = 85² - 13²

Or,  x² = 7225 - 169

Or,  x² = 7056

i.e x = = 84

Hence, the third number to make it right triangle = 84   Answer
