Answer:

x= [tex]\sqrt{113}[/tex]

Step-by-step 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
  • [tex]\sqrt{113}[/tex]=C
