Answer:
is shown below
Explanation:
We are given a side length and an angle
We know that the sine of an angle is the opposite divided by the adjacent side length. We will use this because the picture requires the opposite side length and we are given the adjacent side length.
We know that sin=opposite/adjacent
so we can use sin(39)= x/30
and now we can multiply both sides to single out x
30*sin(39) = x
calculate the value and that is your answer
