This problem is better understood with a given figure. Assuming that the flight is in a perfect northwest direction such that the angle is 45°, therefore I believe I have the correct figure to simulate the situation (see attached).
Now we are asked to find for the value of the hypotenuse (flight speed) given the angle and the side opposite to the angle. In this case, we use the sin function:
sin θ = opposite side / hypotenuse
sin 45 = 68 miles per hr / flight
flight = 68 miles per hr / sin 45
<span>flight = 96.17 miles per hr</span>

Missing part of the question:
Fill in the table above to show the area of each section (see attachment for table)
The area of each section is calculated as:
For the Swing set
For the Slide
For the Pathway
The total area is:
Answer:
The coordinates of the mid-point of JL are (-5 , 2)
Step-by-step explanation:
If point (x , y) is the mid-point of a segment whose end-points are and
, then
and
∵ JL is a segment
∵ The coordinates of J are (-6 , 1)
∴ = -6 and
= 1
∵ The coordinates of L are (-4 , 3)
∴ = -4 and
= 3
Lets use the rule above to find the mid-point of JL
∵
∴ x = -5
∴ The x-coordinate of the mid-point is -5
∵
∴ y = 2
∴ The y-coordinate of the mid-point is 2
∴ The coordinates of the mid-point of JL are (-5 , 2)
