Prove that tan 2A (20OSA - Sec A)=2 sin A

C.

Step-by-step explanation:

First, isolate the y:

First, since there is no "equal to", we can ignore B and D since their lines are shaded.

Since the y is greater than, we need to pick the graph that is shaded above the line.

The answer is C as the shaded portion is above the graph and the graph is dotted.
