The scuba club is taking another trip. The scuba leader’s watch shows that they have swam down -60 feet. A underwater cavern is at -125 feet and they hope to make it down without any accidents. Write and solve an equation to represent this situation and nd the number of feet they still need to travel. Explain what each variable in your equation represents.

what is the figure? attach a picture.

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

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
