Question

If you give me the answer you get 15 points

Answer 1

I will use the Pythagorean Theorem, where leg squared plus the other leg squared = the hypotnues squared

steps:

5

`{5}^(2) + {7}^(2) = {x}^(2)`

5 squared = 25

7 squared = 49

`74 = {x}^(2)`

then square both sides

square root of 74 is 8.6

therfore x= 8.6

Answer 2

8.6 units I think

Explanation: 7 squared is 49. 5 squared is 25. 49+25=74. The square root of 74 rounds to 8.6 when you plug it into a calculator :)
