the angle subtended at center by arc AC = 160 the kite formed as 1 angle = 160 and 2 = 90 degrees so angle ABC = 369 - (90+ 90 + 160)

work out whats in the parentheses first: 360 -(90+90+160) = 360 - 340 = 20

hope you follow it ok - a kite is an example of a quadrilateral ( 4 sides) where the sum of the 4 angles = 360 degrees
