Question

Anyone have any clue what this is going to be

Answer 1

c = 12.7

Explanation:

this is an example of the pythagorean theorem.
`a^(2) +b^(2) =c^(2)`

first you square a and b
`9^(2) =81`

then you add a and b
`81+81=162`

finally you find the square root of 162 and round it to the nearest 10th

√162= 12.7279 rounded to the nearest 10th 12.7
