Answer:
15
Step-by-step explanation:
you can easily use this for it a^2 + b^2 = c^2 where x would be c. after you plug everything in, take the square root of what you got for a^2 + b^2, that will give you x
z=-25.4
Add 11.5 to both sides of the equation, then simplify. Multiply all terms by the same value to eliminate fraction denominators
-0.4
I am pretty sure
