Question

Solve for x. Round to the nearest tenth of a degree, if necessary.

I need help- What’s the answer? I have ten of these-

Answer 1

Use SOH CAH TOA

sin(x) = opp/hyp
cos(x) = adj/hyp
tan(x) = opp/adj

sin(x) = 3.9/8.1
sin(x) = 0.481

Inverse sin of 0.481 = 28.8 degrees

Each answer should be between 0 and 90 :)
