What is the value of x if (13,84, x) is a Pythagorean triple?

85

Step-by-step explanation:

13 x 13 = 169

84 x 84 = 7056

7056 + 169 = 7225

The square root of 7225 is 85 so that's your answer.

x = 85

Step-by-step explanation:

Formula

a^2 + b^2 = c^2

Givens

a = 13 b = 84 c = x

Solution

13^2 + 84^2 = x^2 Substitute the givens into the formula 169 + 7056 = x^2 Add the left 7225 = x^2 Take the square root of both sides. sqrt (7225) = sqrt (x^2) x = 85
