but.... which is it? the + or the -? well, we know that tan(θ) > 0, is another way to say that the tangent of the angle is positive, now, for the tangent to be positive, since it's opposite/adjacent both opposite and adjacent have to be the same exact sign, now, we know the opposite is +2, so that means the adjacent has to be the same sign, thus is the positive version 3√(5)
thus
W- (3,4)
Z- (-1,1)
X-(-1,-3)
Y-(-4,1)
Answer:
$32.13
Step-by-step explanation:
Initial price = $36.00
