If they equal 720 degrees,

x-20+x-60+x-40+130+120+110= 720

3x-120+360=720

3x+240=720

Subtract 240 on both sides.

3x=480

x=160

Plug it into angle A:

(x-60)

160-60= 100 degrees

miss Akunina [59]

It is now possible to find the margin of error, the reason being that the confidence level is not given. However the 'standard error' of the sample mean can be found as follows:
$Standard\ error=\frac{\sigma}{ \sqrt{n} }=\frac{0.043}{ \sqrt{15} }=0.011103$
Converted to a percentage, we get 1.11% which is the third choice of answer.

A farmer wants to fence in a rectangular plot of land adjacent to the north wall of his barn. no fencing is needed along the bar

Digiron [165]

Let the length of the northern side be x and length of the west sides be y. The cost of fence is:
C=10x+10y+5y

and the area enclosed be A=xy
10x+15y=4000
x=400-1.5y
A=400y-1.5y^2
A is maximized when y=400/3 and x=200
