So your answer is Option C.
Answer:
D. 24 ft
Step-by-step explanation:
The slope of 1/3 means the rise is 1/3 the run for each half of the span. The rise is shown as 4 ft, so the half-span is 3·4 ft = 12 ft.
The span of the roof is 24 ft.
The length of its diagonal in terms of r and s is √r² + s²
In order to get the length of the diagonal of a triangle, we will use the Pythagoras theorem:
Pythagoras theorem states that the sum of the square of the diagonal is equal to the sum of the square of the other two sides.
Given the following
Length = r feet
width = s feet
The diagonal "l" will be expressed as;
l² = r² + s²
Take the square root of both sides
√l² = √r² + s²
l = √r² + s²
Hence the length of its diagonal in terms of r and s is √r² + s²
