A contractor is roofing a house. The contractor considers a roof to be steep when the roof rises 7 in. or more for every 12in. it runs. The following graph is a model of how steep the roof is. Does the contractor believe the roof is steep? What is the slope of the roof?

answer:

what is your question that you ask

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

hello umm i don't understand your question can you explain it more pls
