Question

Use Pythagorean Theorem to solve for x.

HELP ME PLZZZZ!!!! ASAP

Answer 1

Answer:
`2√(22)`

Explanation:

Pythagorean theorem:
`a^(2) +b^(2) = c^(2)`, where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

`9^(2) +b^(2) = 13^(2)`

`81 +b^(2) = 169`

Since we don't know what
`b^(2)` is, we're going to isolate it by subtracting 81 on both sides

`b^(2) = 88`

We have to square root both sides in order to find out b (or x in the problem).

`\sqrt{b^(2)} = √(88)`

When you put this on a calculator it would result in
`2√(22)` which is the answer d in the problem.
