1530 subtracted to 180 = 1350
145 subtracted by 180 = -35
840 subtracted by 480 = 360
-184
180 add 180 = 360
If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!
180 540 ÷ 360 = 1 r 180 360 ÷ 180 = 2 r 0 ⇒ gcf = 180
360 + 180 = 540

180:360 = 1:2.
180/360 = 1/2
LCM(8, 180) = 360.
