Starting at the fourth floor, an elevator goes down 3 floors and ther up 8 floors. At which floor does the elevator stop? what are you being asked to do?

what is a good way to set up the problem visually?

Floor 9

Step-by-step explanation:

Well 4-3 =1+8=9 so the 9th floor

the answer is d on edge

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
