The total length of the stage is 76 feet. if the trap doors are centered across the stage, what is the distance from the left side of the stage to the first trap door?
me step by step : )

76-26 1/2 = 49 1/2 / 2 = 24 3/4

∠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°
