Answer:
78°
Step-by-step explanation:
The angular distance of an arc is twice the angle that forms it if that angle lies of the edge of the circle.
By this, Arc AK has angular distance 158°.
Arc JL = 202°.
Arc KL = 122°.
By subtracting these we get 80° for Arc JK.
Arc KA = 158°.
Arc AJ = KA - JK
AJ = 158-80
AJ = 78°
7 - 4 = 3 that will be your answer
