Answer:
Distance from point A to the top of the building(hypotenuse)=
Height of the landscaper=

Explanation:
Given:
Distance from point A to bottom of building = 5 feet
Angle of depression from the top of building = 45°
We see that the triangle formed is a special 45-45-90 right triangle
The sides of such triangle is given by:
Leg1 =

Leg2=

Hypotenuse =

We know the

So we can find all the sides of the triangle:
Leg1 =

Leg 2 =

Hypotenuse=
It is shown in figure attached.
Distance from point A to the top of the building(hypotenuse)=
Height of the landscaper=
