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:
12X^-3
Step-by-step explanation:
12X^15 / 3X^12 = 0. The properties of exponents would say that we have to subtract the exponents in division, but we need the same bases first. In order to get the bases the same we need to divide both sides by 1/4. That will make 12 stay 12 and 3 become 12. Now we subtract the exponents using the properties of exponents with the same base. We end up left with 12x^-3.
I apologize if I made an error. I would be careful since I'm not to sure about my answer myself.
