Answer:
3/5
Explanation:
the function sin is equivalent to the opposite side of the angle over the hypotenuse
your opposite side is 12
using Pythagorean theorem we can find the hypotenuse (12 squared + 16 squared = 400) finding the square root of 400 gives you the hypotenuse (20)
opposite/hypotenuse is 12/20 which simplified is 3/5
