Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
