Refer to the photo. Use Pythagorean theorem of a^2 + b^2 = c^2

Irina-Kira [14]2 years ago
3 0

Answer:

Step-by-step explanation:

We will need to rewrite the Pythagorean Theorem

A^2 + B^2 = C^2

Substitute. tIn this case:

18^2 + x^2 = 82^2

Subtract 18^2

x^2 = 82^2 - 18^2

In order to get x alone, take the root:

x = sqrt(82^2 - 18^2)

And solve:

x = 80
