Since arc CD is 100 degrees, the rest of the circle must be 260 degrees. Since the rest of the circle is made up of two equal arcs, then arc BC must be half of 260 degrees. Thus, the answer is 130 degrees, C.
Answer with explanation:
⇒A segment ,
is equivalent to
.
⇒We can assert this by this way, if Distance between Two points A and B is 6 unit, then Distance between B and A will be 6 unit also.
So,

FM−→−⇒MF−→−
Option A
If the y intercept isn't -5 go to ur coordinate that is given and find where the y intercept is and plug in the y intercept to y=mx+b
