I need help with this word problem please A person in a lighthouse, that is 315ft high, spots a boat in trouble. The angle of depression to the boat is 21°49ʹ. How far from shore is the boat?

NO LINKS

786.9 feet to the nearest tenth.

Step-by-step explanation:

In the triangle formed between the boat, base of the lighthouse and the top of the lighthouse, the opposite side to angle 21 49' is the height of the lighthouse and the distance (d) of the boat is the adjacent side.

So we have:

tan 21 49 = 315 / d

d = 315/ tan21 49

= 786.89 ft.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
