The relation between arc length and exterior angle is given in the figure.

Now we are given far arc length as DE =124

We are given near arc length as BC = 36

So plugging in the formula to find measure of angle A:


angle A=(far arc-near arc)/(2)


angle A=(124-36)/(2)


angle A=(88)/(2)

Angle A = 44 degrees

Answer : A) 44 degree
