Prove that: 1 - cos 2Θ is identical to: tanΘsinA

where A is an expression to be found.
what is the value for A

alright well the answers to your question is

2xy/9 hope this have a nice day : )

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
