In the figure, the value of a is 5/3
How to find the value of a
Based on the decryption of the figure, Angle BOC and 30 degrees are complementary angles
hence angle BOC is 60 degrees
central angle = intercepted arc, hence minor arc BC = 60
Major arc BDC = 360 - 60 = 300
given that arc BDC = aπ
aπ = 300
aπ = 5/3 π
a = 5/3
