Answer: 7
Add up the values to get 4+10 = 14
Then divide that result over 2 to get 14/2 = 7
This is using the midpoint formula.
Answer:
Step-by-step explanation:
Let's call the balloon's height above the ground and the horizontal distance between the balloon and the first milepost.
If the angle of the depression of this milepost is 24 degrees, we can say the following:
<em>(equation 1)</em>
For the next milepost, the horizontal distance between the balloon and tihs milepost will be and the angle of depression will be 20 degrees, so we can say the following
then, replacing from <em>equation 1</em>
Resolving, we'll find the value of
So, the balloon's height above the ground is 1.99miles
261 is the correct answer.
