Sagot :

Answer:

The angle of elevation of the top of the tree is 43°.

Solution:

tan (angle) =  

14 ÷ 15 = 0.93333333

acrtan(0.93333333) = 43°

Step-by-step explanation:

One of the given from the problem is Obiwan's distance form the tree which is 15 m. This distance will serve as the horizontal line of sight of adjacent side of the angle. Another given was that the tree is 15 m high. It was also mentioned that Obiwan is 1 m tall. You need to subtract the height of Obiwan from the height of the tree to get the opposite side of the angle. Then use the formula for tangent to get the tangent of angle of elevation. Upon getting the tangent of the angle, just do the inverse function which is arctangent to get the actual angle.
