Astore sells self-serve frozen yogurt sundaes. the function c(w) represents the cost, in dollars, of a sundae weighing w ounces. an appropriate domain for the function would be 1: integers 2: rational numbers 3: nonnegative integers 4: nonnegative rational numbers

∠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°

it is not that hard all u have to do is plot the graph
