Answer:
5.385164807
Explanation:
For this problem you can use Pythagorean Theorem which is a^2 + b^2 = c^2.
- a^2 would be a side you have, we'll use 2.
- b^2 would be the other side, which would be 5.
- Do a^2 + b^2 which would be 2^2 + 5^2
- 2^2 = 4
- 5^2 = 25
- 25 + 4 =2 9
- Square your number -
- This would get you 5.385164807.
