The slope of a roof is called the pitch and is defined as follows:
pitch = rise of roof
½ span of roof
find the pitch of a roof if the rise is 12 feet and the span is 30 feet.
find the pitch of a roof if the rise is 4 feet and the span is 24 feet.

a) 4/5

b) 1/3

Step-by-step explanation:

Put the numbers in the formula and evaluate.

a) pitch = (rise)/(1/2·span)

= (12 ft)/(1/2·30 ft) = 12/15 = 4/5

___

b) pitch = (4 ft)/(1/2·24 ft) = 4/12 = 1/3

step-by-step explanation:

c. side angle side. u shares the same sides
