In order for this to be solved we need to know the angle of each side. This question cannot be solved unless you show us the Diagram. I'll be happy to help once that is settled<span />
Answer:
<h3>28feet</h3>
Step-by-step explanation:
Let the wallpaper be a rectangle
Area of a rectangle = Length * Width
A = LW
Perimeter P = 2L+2W
If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.
60 = 2L + 2(2)
60 = 2L + 4
2L = 60-4
2L = 56
L = 56/2
L = 28
<em>The minimum length that will be purchased to cover the wall is 28 feet</em>

Answer:
tan 60 = √3
Step-by-step explanation:
using SOH CAH TOA
tan theta = opposite/adjacent
Let the side opposite to angle 60 degrees be x
Hence;
tan 30 = 5/x
x = 5/tan 30
x = 5/1/√3
x = 5√3
Get tan 60
tan 60 = 5√3/5
tan 60 = √3
