Answer:
17
Step-by-step explanation:
The given is a right triangle and the side length that is represented by x is called hypotenuse. Now:
The square length of hypotenuse is equal to the sum of square value of two legs:
9^2 + 15^2 = x^2
81 + 225 = x^2
306 = x^2 find the square root of both sides
17 = x
This is an approximate value since they asked us to find the value nearest tenth, if not we can write the root of 306 as [tex]\sqrt{306}[/tex] only
