Answer:
The ans is correct. But I think C is also correct.
Step-by-step explanation:
Answer:

Step-by-step explanation:
<u>Trigonometric Identities</u>

<u>Trigonometric ratios</u>

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Using the trig ratio formulas for cosine and sine:
Therefore, using the trig identities and ratios:

T is equal to any number just choose one. In the end they both end up with t+1. I hope my answer is correct and sorry for my handwriting.
