Step-by-step explanation:
nm=16
m=16/n
m=16/8
m=2
OK so we know that the other side is 12 because the right triangle has to have two sides that add up to the hypotenuse, and I believe it gives you the answer in the question because you are trying to find x which it says x is the angle, and since its a right triangle, it would be 90°

Hi there!
Since this is a one-step equation, we can solve it in one step.
This step is multiplying both sides by 4 to isolate x:
x=16*4
x=64
Therefore, x=64.
Hope it helps!
