Find the slope by using the formula
Plug in the numbers.
Write it in point slope form first
y - y1 = m(x - x1)
y - 7 = 7/8(x - -2)
y - 7 = 7/8x + 1.75
+ 7 +7
y = 7/8x + 8.75
Our final equation would be: <span>y = 7/8x + 8.75</span>

In the picture below, h is height of building and x is the distance the base of the ladder is away from the base of the building.
We use trigonometry to find x, particularly the cosine function.
cos(29.37°) = x/32
cos(29.37°)(32) = x
27.8870633052 = x
We now round off to the nearest hundredths, which means to two decimal places.
27.89 feet = x
