42 feet.

Step-by-step explanation:

We have been given that a flagpole is 50 feet from a point on the ground. The angle of depression from the top of the flagpole to the same point on the ground is 40°.

We can see from the attachment that side 50 is adjacent and side h is opposite side to angle 40 degrees.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

$\text{tan}(40^{\circ})=\frac{h}{50}$

$\text{tan}(40^{\circ})*50=\frac{h}{50}*50$

0.839099631177*50=h

41.95498155=h

h=41.95498155

$h\approx 42$

Therefore, the height of the flagpole is 42 feet.

Aflagpole is 50 feet from a point on the ground. the angle of depression from the top of the flagpol
