Answer:
The answer to your question is 38.7
Step-by-step explanation:
To solve this problem, we must use trigonometric functions. The picture shows the opposite side and the adjacent side so we must use tangent to find Ф.
tan Ф = [tex]\frac{opposite side}{adjacent side}[/tex]
Opposite side = 4
adjacent side = 5
tan Ф = [tex]\frac{4}{5}[/tex]
tan Ф = 0.8
tan⁻¹Ф = 38.7°
