Using trigonometric identities, it is found that the sine and the tangent of the angle are given as follows:
.
<h3>How do we find the sine of an angle given the cosine?</h3>
We use the following identity:

In this problem, the cosine is:

Hence the sine is found as follows:




Second quadrant, so the sine is positive, hence:

<h3>What is the tangent of an angle?</h3>
The tangent is given by the <u>sine divided by the cosine</u>, hence:

Hence:

Answer:
C
Step-by-step explanation:
4x-5+x=180. Add 5 to both sides
5x=185. Divide by 6
X=37
180-37=143
