Seven halves is equal to how many wholes and half

∠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°

its 50 miles away from the starting point

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
