Question

a plain takes off at an angel of 20 degree. assuming a constant speed and trajectory, by the time it has travelled 25 kilo meter horizontally, how h8gh it will be fly​

Answer 1

9.10 km to the nearest hundredth.

Explanation:

We have a triangle whose adjacent side is 25 km and angle 20 degrees.

If h is the height we have the equation:

tan 20 = h / 25

h = 25 tan 20

= 9.099 km.
