Answer:
26.2655 miles
Step-by-step explanation:
Whenever possible, draw a diagram. I've attached a picture of the balloon and the lines of depression (not drawn to scale, of course).
As you can see, the angles of depression form alternate interior angles with the ground (angles of elevation). So these angles are also 13° and 39°.
We can use the tangents of these angles to find the base lengths of the two triangles that are formed.
tan 13° = 4 / a
a = 4 / tan 13°
tan 39° = 4 / b
b = 4 / tan 39°
So the total distance is:
a + b
= 4 / tan 13° + 4 / tan 39°
≈ 22.2655
Answer:
1.875 or cups of pretzel
Step-by-step explanation:
The number of cups needed is equivalent to the probability of pretzel in the mix times the number of cups in the mix.
-The probability of pretzel is :
We multiply this probability by the number of cups of the mix:
Hence, 1.875 or 1/7/8 cups of pretzel is needed.
