Blue’s Gym is planning to build a new swimming pool. The shaded area shown is a scale drawing of a rectangular swimming pool surrounded by a brick walkway. Each square brick on the drawing represents an actual square brick with side length of 3 feet. What are the dimensions of the actual pool? Assume the length is the longer dimension.

i think the length is 12 and the width is 17

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

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
