Question

Based on the figure, select all true equations.

Answer 1

B, C, E, F

Explanation:

Solve for the missing angle first (which is 42°)

Listing all of the basic trig ratios (sohcahtoa):

sin x = opp/hyp

cos x = adj/hyp

tan = opp/adj

sin 48° = a/c

cos 48° = b/c

tan 48 = a/b

sin 42° = b/c

cos 42° = a/c

tan 42° = b/a
