Along a long, straight stretch of mountain road with a 7.2 % grade, you see a tall tree standing perfectly plumb alongside the road. From a point 450 feet downhill from the tree, the angle of inclination from the road to the top of the tree is 6.2 degrees. Use the Law of Sines to find the height of the tree to the nearest tenth of a foot.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
