Answer:
A
Step-by-step explanation:
Since m∠JOK is 1/5th of the measure of the full circle (we know this because 72° is 1/5th of 360° and 360° is the measure of the whole circle), we know that the measure of minor arc JK will be 1/5th of the circumference of the circle. C = 2πr and we know that r = 5 so the circumference is 10π. 1/5th of that is 2π.
Answer:
Angle 2
Step-by-step explanation:
<u><em>Vertical angles are congruent opposite angles when two lines intersect.
Line E A and B N intersect each other to form Angles B C A and E C N, or angle C and angle 2, which are congruent to each other as well, which makes them vertical to each other.</em></u>
