Cos = adjacent / hypotenuse
cos B = 4/5
B = cos^-1 (4/5)
B = 36.869897....
B = 36.87° (nearest hundredth)
Angle B = 36.87°.

Answer:
Option A is the correct answer
Step-by-step explanation:
![f(x)=\sqrt[3]{2x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%5B3%5D%7B2x%7D)

![\bigg(\frac{f}{g}\bigg)(x)=\frac{\sqrt[3]{2x}}{4x+1},\:x\neq -\frac{1}{4}](https://tex.z-dn.net/?f=%5Cbigg%28%5Cfrac%7Bf%7D%7Bg%7D%5Cbigg%29%28x%29%3D%5Cfrac%7B%5Csqrt%5B3%5D%7B2x%7D%7D%7B4x%2B1%7D%2C%5C%3Ax%5Cneq%20-%5Cfrac%7B1%7D%7B4%7D)
Because by plugging x = -1/4 denominator of the fraction would become zero.
Division by zero is not defined.
