Since RS bisects PQ at point R, then R is the midpoint of PQ.
PQ = 14 <em>given</em>
PR = RQ <em>definition of midpoint</em>
PR + RQ = PQ <em>segment addition postulate</em>
RQ + RQ = PQ <em>substituted PR with RQ</em>
2RQ = PQ <em> simplified (added like terms)</em>
2RQ = 14 <em> substituted PQ with 14</em>
RQ = 7 <em>divided both sides by 2</em>
Answer: 7 cm
The required value is the angle theta and the value of the cosine of the angle is 0.9659
Given the expression of sine of an angle expressed as;

For us to get the cosine of the angle, we need to get the value of theta first as shown:

Next is to get the value of cos theta
