Answer:

7.4

Step-by-step explanation:

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)
