Answer:

Explanation:

They are all solved kind of the same way. If the vertex of the angle is outside of the circle, subtract the intercepted arcs and divide by 2

for 15) one arc is marked but you can figure out the other arc because there are 360 degrees in a circle 360 - 102 = 258. So the two arcs are 102 degrees and 258 degrees.

some of the problems you can set up the equation and solve.

17) 63 = {(360-x) - x} /2 multiply by 2

126 = {(360-x) - x} combine like terms

126 = 360 - 2x subtract 360

-234 = -2x divide by -2

117 = x

? = 117 degrees

good luck
