From a hot air balloon that is between his house and parade, john measures the angle of depression to his house of 35 and to the
igomit [66]

4500 feet

Step-by-step explanation:

We can begin by finding x using the tangent rule;

The tangent of the angle = the length of the opposite side / the length of the adjacent side

Tan 35 = 3500 / x

X = 3500 / tan 35

X  = 3500 / 0.7

X = 5000

Now that we have x we can calculate the value of ? using the same tangent rule;

Tan 42 = ? / 5000

? =  tan42 * 5000

? = 0.9 * 5000

? = 4500
