Answer:
28°
Step-by-step explanation:
For this problem, we are given the leg length opposite the angle x and the hypotenuse. This perfectly describes the trig function, sine. We can set up an equation:
opposite / hypotenuse = sin(x°)
We can substitute in the sides:
7 / 15 = sin(x°)
Now, to find x, we can evaluate the inverse of sin or arcsin on the ratio 7 / 15
arcsin(7 / 15) = x° = 27.81813928°
This rounds to 28°
