A roller coaster climbs 110 feet from ground level then drops 65 feet before climbing another 135 feet. How far does the coaster
2 answers:
Answer:
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.

Answer:
The missing height is approximately 78.8011 feet.
Step-by-step explanation:
To solve for the height of the kite, you need to use a trigonometry function called sine. Sine - or sin when used to calculate - is most commonly used for right triangles, and the sine of a right triangle angle is equivalent to the side opposite (or the only side of the right triangle that does not help create that angle) of the angle divided by the hypotenuse of the right triangle. So you can now create the following function to solve the height: sin(52°) = where x represents the unknown height of the kite. From there, you can get that
52°
, which equals approximately 78.8011 feet. Since there isn't a specific decimal place to round to, I rounded the answer to four decimals. If your teacher asks you to round to a specific place value, use 78.8011 to get your simplified answer.
