Solve for x. Help Help Help Help Help, I tried dividing 17/2 which gave me 8.5 but it’s wrong

Answer:
x = 15.9
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + x^2 = 17^2
36+ x^2 = 289
x^2 = 289-36
x^2 =253
Take the square root of each side
sqrt(x^2) = sqrt( 253)
x = 15.90597
Rounding to the nearest tenth
x = 15.9
