Answer:
9
Step-by-step explanation:
Divide 135 by 15.
If we draw RU and RT we see the radii are perpendicular to the tangents, so TRU and TZU are supplementary. Since TZU=XZY=15 degrees, TRU=180-15=165 degrees. So the other side is 360-165=195 degrees as is the measure of arc TSU
Answer: 195 degrees
-14i is the answer to the equation
