Answer:
The answer to your question is 63.4°
Step-by-step explanation:
Data
m∠B = ?
Opposite side = 10
Adjacent side = 5
To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.
tan B = Opposite side / Adjacent side
-Substitution
tan B = 10/5
-Simplification
tan B = 2
-Result tan⁻¹B = B = 63.43
Rounded to the nearest tenth = 63.4°
