Answer:
b.
Explanation:
Before we begin, remember that:
tan α =
Now for the given, we have:
cos θ - tan θ * cos θ = 0
cos θ -
* cos θ = 0
cos θ - sin θ = 0
cos θ = sin θ
Now, divide both sides by cos θ, we get:
1 = tan θ
Following the ASTC rule, we know that the tan function is positive in the first and third quadrants.
This means that:
either θ =
or θ = π + =
