Question

The exact value of x

Answer 1

x=
`√(113)`

Explanation:

For this problem, you need to know the Pythagorean Theorem, which is A²+B²=C².

1. First, write down what you know. You need to find the longest side, which is x. The other sides are 8 and 7.
2. To solve, you need to plug in A with 8 and 7 with B.
3. Now solve:

• 8²+7²=C²
• 64+49=C²
• 113=C²
• 
  `√(113)`=C
