Aroller coaster climbs 110 feet from ground level then drops 65 feet before climbing another 135 feet. how far does the coaster need to drop or climb to be back at ground level. a) drop 70 feet b) drop 180 feet c) climb 70 feet d) climb 180 feet

B) Drop 180 feet.

Step-by-step explanation:

We have been given that a roller coaster climbs 110 feet from ground level then drops 65 feet before climbing another 135 feet. We are asked to find the height that coaster need to drop or climb to be back at ground level.

First coaster climbs 110 feet, so it will be a positive elevation. Then it drops 65 feet, so it will be a negative elevation.

The coaster again climbs 135 feet, so it will be a positive elevation.

Therefore, the coaster needs to drop 180 feet to be back at ground level.

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
