theta is in the fourth quadrant where the cosine is positive.
the third side in the triangle = sqrt (4 - 2) = sqrt2
So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)
tan theta = - sqrt2 / sqrt2 = -1
Happy to help :-)

all you have to do is add up all of the sides.
You need to find 24% of $7000 because that's the total interest over the course of 3 years. The answer is $1680
The answer is a. b>-2 because
6b<24
b< 24/6
b<4
And
4b+12>4
4b>4-12
4b>-8
b>-8/4
b>-2
