can anyone help me with this question ?

OpenStudy (cwrw238):

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)

OpenStudy (cwrw238):

can you work that out?

OpenStudy (cwrw238):

529?

OpenStudy (cwrw238):

thats alright

OpenStudy (cwrw238):

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

OpenStudy (anonymous):
