Setting it up as a fraction will help us see the simplification process a bit easier.

$\frac{am}{an}$

a/a = 1, so they cancel each other out, leaving us with simply

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

Zarrin [17]

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

$B=36.87$

What is the measure of an angle whose complement and supplement equal 200?

dmitriy555 [2]

The complement is 90-n and the supplement is 180-n. If I understand your wording properly, we now know that 90-n + (180-n) = 200.

-2n + 90 + 180 = 200. Solve for n: 270-200 = 2n, so n = 35 degrees.
