Answer 1

Use trigonometry

Answer 2

Hint: Use sin(76.6)

Answer 3

You there?

Answer 4

yes

Answer 5

Use sin 76,.6

Answer 6

sin76.6 = r / r + 110?

Answer 7

sin76.6 = r / (r + 110)

Answer 8

ok, hold on while I distribute. I think I figured out where I messed up. I wrote r + 10 instead of r + 110
