Answer:
7.4
Step-by-step explanation:
Because we have the adjacent length and we are trying to find the opposite of the angle we will use tan.
Tan = [tex]\frac{opposite}{adjacent}[/tex]
Rearrange this to find opposite...
Opposite = Tan * Adjacent
Opposite = tan(42) * 8.2
Opposite = 7.4 (rounded to the nearest tenth)
