The ratio of the number of hippos to the number of crocodiles at a watering hole is 4:3 . Draw a double number line diagram that would show the number of crocodiles if there were 20 hippos

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
