A plane is 3.5 miles above the ground. The pilot sights the airport at an angle of depression of 20 ∘. To the nearest tenth of a mile, what is the ground distance between the plane and the airport? Enter the ground distance to the nearest tenth of a mile.

9.6 miles

Step-by-step explanation:

Looking at the diagram we have everything we need except for the adjacent.

We know the formula of the  tan∅ =

where ∅ = 20 and opposite is 3.5.

Solving for adjacent yields 9.6 miles.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
