If you draw a diagram of this, your given values of the resulting triangle give you the sides opposite and adjacent of the angle. The formula that uses these sides is tangent.

The tangent of an angle is equal to the ratio of the opposite side over the other non-hypotenuse side (adjacent).

Therefore;

tan(40)=70/x
0.83909963117=70/x
0.83909963117x=70
x=70/0.83909963117
x=83.4227514823

Where x is the length of the string in feet.

- How is the formula for the perimeter of a rectangle an application of the Distributive Property
N76 [4]
Distributive is
a(b+c)=ab+ac
ab+ac=a(b+c)

perimiter of a rectangle=distance around

we have
P=L+W+L+W if we go around
so
P=L+L+W+W
P=2L+2W
undistribute 2
P=2(L+W)
