The distance between two cities on a map is 15.6 cm. The scale for the map is 1 cm = 5 mi. What is the actual distance in miles? Round to the nearest tenth if necessary

∠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°

i think the answer is b.

step-by-step explanation:

not 100% sure though.

any options?
