I might be wrong but Im sure it's -5
Answer:
Step-by-step explanation:
We are given that:
And we want to find the value of cos(A) and sin(A).
Recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the opposite side measures 2<em>ab</em>, and the adjacent side measures <em>a</em>² - <em>b</em>².
Using the Pythagorean Theorem, solve for the hypotenuse:
Thus, our hypotenuse is given by <em>a</em>² + <em>b</em>².
Cosine is the ratio between the adjacent side and the hypotenuse. Thus:
And sine is the ratio between the opposite side and the hypotenuse. Thus:
In conclusion:
I believe the answer is a
