A scale drawing of an apartment shows the living room length as 5.7 inches. The scale on the drawing is 1 inch = 3 feet. What is the actual length , in feet, of the living room?

17.1 feet

Step-by-step explanation:

Scale drawing = 5.7 inches

scale = 1 inches = 3 feet

If 1 inches = 3 feet

5.7 inches = feet

solving for , we cross-multiply

x 1 = 5.7 x 3

= 17.1 feet

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
