Answer: 12.3 ft.

Step-by-step explanation:

In the given picture we can see there is a right triangle with hypotenuse 15 ft.

Using trigonometry in the given right triangle, we have

$\cos35^{\circ}=\frac{\text{Side adjacent to}\ 35^{\circ}}{\text{Hypotenuse}}\\\\\Rightarrow\ 0.81915204428=\frac{A}{15}\\\\\Rightarrow\ A=0.81915204428\times15\\\\\Rightarrow\ A=12.2872806642\approx12.3\ ft.$

Hence, the length of rope A = 12.3 ft.

Wayne is hanging a string of lights 78 feet long around the three sides of his piano, which is adjacent to his house. The length

Sauron [17]

Answer:

The width is 18 feet and the length is 42 feet

Step-by-step explanation:

Let x feet be the width of the patio. The length of the patio is 6 feet longer than twice it’s width, then the length of the patio is 2x+6 feet.

Wayne is hanging a string of lights 78 feet long around the three sides of his patio, which is adjacent to his house. The side with length 2x+6 feet is adjacent to the house, so Wayne is hanging a string along three sides with lengths x ft, x ft and 2x+6 ft.

Hence,

$x+x+2x+6=78\\ \\4x=78-6\\ \\4x=72\\ \\x=18\ ft$
