Answer: Choice C</h3>
================================================
Work Shown:
Reference angle = P
Opposite side = QR = 8.5
Adjacent side = QP = 16
tan(angle) = opposite/adjacent
tan(P) = QR/QP
tan(P) = 8.5/16
tan(P) = 0.53125
tan(P) = 0.53
The correct answer is none of the above.
<h3>What is a line?</h3>
A line is defined as the shortest distance between two points and the point where two lines meet is known as an angle.
From the given figure, the measure of angle a and b are supplementary since the sum of the angles is not 180 degrees.
They are not vertical angles since they do not meet at a point of intersection
The measure of angle a and b are complementary since the sum of the angles is not 90 degrees. Hence the correct answer is none of the above.
