(2x-2)+(15x+29)=180
17x+27=180
17x=180-27
17x=153
x=153/17 = 9
Answer is D
That would be Quadrant 1, which is the quadrant in the top right corner.
Sin corresponds to the y-value, so sin would be positive at Quadrants 1 and 2.
Tan, which is y/x (sin/cos), is positive at Quadrants 1 and 3.
So at quadrant 1 is where both sin and tan are positive.
A = $ 10,283.79
A = P + I where
P (principal) = $ 10,000.00
I (interest) = $ 283.79
