A farmer has 480 feet of fence to enclose a rectangular area. what dimensions for the rectangular result in the maximum area enclosed by the fence what us the length and width?

Length = 120 feet

Width = 120 feet

Step-by-step explanation:

Rectangle with maximum area is a square

X = side of a square

4X = 480 feet of fence

X = 120 feet

Length = 120 feet

Width = 120 feet

what does x eaqual

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
