In the diagram below, AB and BC are tangent to Oo. Which equation could be solved to find x, the measure of AC?
58. B
238"
= x
A. 2 (238 + 58) =
B. (238 + x) = 58
C. }(238 - 58)
D. }(238 - x) = 58
= x

Draw your right triangles.

sin(g) = -3/4: you need to draw the point (x, y) such that y = -3, x < 0, and x2 + (-3)2 = 42

Then cos(g) = x/4, tan(g) = -3/x, csc(g) = -4/3, sec(g) = 4/x, and cot(g) = -x/3

The others are done similarly: use the info given to figure out the (x, y) point, and derive trig ratios from them,
