Answer:
69°
Step-by-step explanation:
TOA is tan(θ)[tex]=\frac{opposite}{adjacent}[/tex]
Reversing the process is [tex]arctan[/tex] or [tex]tan^{-1}[/tex]
[tex]arctan(\frac{4.7}{1.8})=[/tex]
1.205 radians
69.04 degrees
Answer:
B = 69.0 ⁰
Step-by-step explanation:
Using Trigonometric ratio,
tan B = opposite side / adjacent side
tan B = 4.7 / 1.8
tan B = 2.6111
B = arctan (2.6111)
B = 69.0442
Therefore,
B = 69.0 ⁰ to the nearest tenth.
