Answer:
d. -7/25
Step-by-step explanation:
π<θ<3π/2 in third quadrant
tanθ = 4/3
sinθ = - 4/5
cosθ = - 3/5
cos 2θ = cos²θ - sin²θ = (- 3/5)² - (- 4/5)² = 9/25 - 16/25 = - 7/25
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>
