The length of a car's skid mark in feet as a function of the car's speed in miles per hour is given by L=0.04682 0.199s + 0.264. If the length of the skid mark is 220 ft, then what is the speed in
miles per hour the car was traveling?
o 67 miles per hour
o 71 miles per hour
2 miles per hour
o 22 miles per hour

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

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

5+2x=a
