Question

(GEOMETRY HELP PLS) What is the approximate measure of angle F? Use the law of sines to find the answer.

Answer 1

You can just use sine.

Sin(F) = opposite/hypotenuse = 28/40.

F = $sin^{-1}$(28/40)

Plug into your calculator.


44.4

Answer 2

If you use sine
Sin(F)=opp/hyp =28/40
F = Sin - 1(28/40)
Plug it in which equals 
44.4
