Question

AngleB = Round your answer to the nearest hundredth. А 5 ? B С 4.

Answer 1

Answer:

$B=36.87$

Step-by-step explanation:

As we are given the adjacent (a) side and the hypotenuse (h), we can use the cosine function to find the measure of angle B.

Recall that $cos(B)=\frac{a}{h}$

This means that in order to find B, we need to take the inverse of cosine

This gives us

$B=cos^{-1} (\frac{4}{5} )$

From a calculator, we find that the answer of this is

$B=36.869$

When this is rounded to the nearest hundredth, we get

$B=36.87$
