The height of a vertical brace placed 8 ft from the low end of the roof is 6 feet.
An equation is an expression that shows the relationship between two or more variables and numbers.
Slope of roof = ratio of rise to run = rise / run = 9/12 = 3/4
If the brace is placed 8 ft from the low end of the roof, hence:
height of brace = slope * 8 = 3/4 * 8 = 6 ft
The height of a vertical brace placed 8 ft from the low end of the roof is 6 feet.
