Question

An airplane climbs at an angle of 11 degrees with the ground. Find the ground distance it has traveled when it has attained an altitude of 400 feet?

Answer 1

I tried this:

Explanation:

Consider the diagram:

we use trigonometry to write:
`400/x=tan(11^@)`
rearrange:
`x=400/tan(11^@)=2057.8~~2058"ft"`
