Answer:
B:25°
Step-by-step explanation:
Now gets bisected by
.
Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.
We know that one of the angles is so the other angle has to be
also.
Hence, the .
Answer:
see below
Step-by-step explanation:
We assume you want the graph of ...
A graphing calculator or spreadsheet is useful for this.

You know cos(θ) = cos(-θ), so the graph is symmetrical about the x-axis. You can evaluate the function at a few points to find the general outline.
r at 0° = 8
r at 30° ≈ 7.05
r at 45° ≈ 6.19
r at 60° ≈ 5.33
r at 90° = 4
r at 120° = 3.2
r at 135° ≈ 2.96
r at 150° ≈ 2.79
r at 180° ≈ 2.67
