Use the diagram below to answer the question that follows The cross section of the roof of a building shown above has a width of 40 feet and a slope of 45 feet class=

Respuesta :

Making a right triangle:

slope= m= 4/5

y = mx + b

You know that b = 0 because that is your referece. Then:

y = mx

If x = 20ft, then:

[tex]y=mx=\frac{4}{5}\times20=16ft[/tex]

y = h = 16ft
