Please help with number 1 , 2, and 3Number 1

We can use the angle relationship in circles which states that when the angle is outside the circle, the measure of the angle is half the difference of the measures of its intercepted arcs.
[tex]m\angle L=\frac{1}{2}(m\hat{JN}-m\hat{KM})[/tex]In this case, the measure of angle C is:
[tex]m\operatorname{\angle}C=\frac{1}{2}(m\hat{AE}-m\hat{BD})[/tex]Answer[tex]m\operatorname{\angle}C=\frac{1}{2}(m\hat{AE}-m\hat{BD})[/tex]
