Answer:
Step-by-step explanation:
QII means that we take a point in the second quadrant.
We have that y = -9x, so if x = -1, y = -9*(-1) = 9. So we have the point (-1,9).
From this point, we can draw the following right triangle:
First we find the hypothenuse:
h² = 9² + 1²
h² = 82
h = sqrt(82).
Tangent:
Sine:
