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.
