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

Answer:

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.
