A gold mine has two elevators, one for equipment and another for miners. The equipment elevator descends 6 feet per second. The elevator for the miners descends 16 feet per second. One day, the equipment elevator begins to descend. After 22 seconds, the elevator relative to the surface after another 17 seconds? At that time which elevator is deeper?

It should the miners

Step-by-step explanation:

Miners:

17(time) x 16 (feet per second) =  272(distance)

equipment

22 (time) x 6 (feet per second)= 132 (distance)

∠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°
