The answer is D because side 3 is to far from side 1 and side 2 because you cant make a triangle out of those measurements
Here's a tip
if the sum of side 1 and side 2 are greater than side 3 then it forms a triangle
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
You add 8 and 5 so the equation would be 8+5=13
The value of x would be 4m
