Answer:
∠F ≈ 67°
Step-by-step explanation:
Using the tangent ratio in the right triangle then
tanF = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{GH}{FG}[/tex] = [tex]\frac{12}{5}[/tex], thus
F = [tex]tan^{-1}[/tex]( [tex]\frac{12}{5}[/tex]) ≈ 67°
Note ∠F can be found using the sine or cosine ratios as well
