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.
- First, write down what you know. You need to find the longest side, which is x. The other sides are 8 and 7.
- To solve, you need to plug in A with 8 and 7 with B.
- Now solve:
- 8²+7²=C²
- 64+49=C²
- 113=C²
- [tex]\sqrt{113}[/tex]=C
