ZK and ZL are complementary angles. If mZK = (3x + 3)º and mZL = (10x - 4)º, find mZL.
mZL = 24°
mZL = 66°
mZL = 60°
mZL = 50°

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.
