Question

Can someone please help?!

Answer 1

7.4

Explanation:

Because we have the adjacent length and we are trying to find the opposite of the angle we will use tan.

Tan =

Rearrange this to find opposite...

Opposite = Tan * Adjacent

Opposite = tan(42) * 8.2

Opposite = 7.4 (rounded to the nearest tenth)
