A plane ascends at a 40° angle. When it reaches an altitude (height) of 100 feet, how much ground (horizontal) distance has it c
1 answer:
Answer:
119.2 ft.
Step-by-step explanation:
In order to find the ground distance covered, we must find what the values given are for. 40° is the angle that is θ. 100 ft is the altitude, which is the height. We must find the ground distance covered. So we can find using the tan formula:
tanθ = Opposite side ÷ adjacent side
The opposite side is the height and the adjacent side is the ground distance, which we are going to assume as x. So when all values are substituted:
tan 40° = 100 ÷ x
So,
x = 100 ÷ tan 40°
x = 119.2 ft

First, draw a diagram to visualize the situation:
As we can see, the difference between the x-coordinates of the points is the length of one leg of a right triangle, and the difference between the y-coordinates is the length of the other leg.
Then, for the given points (-5,4) and (8,-3), the distance given by the Pythagorean Theorem is:
Therefore, the distance between the points (-5,4) and (8,-3) is: √218.
