Answer:
the height of the tree to the nearest tenth of a meter is 13.8 meters
Step-by-step explanation:
The computation of the height of the tree is shown below:
Given that
Distance from the tree is 10 meters
And, the angle of elevation of the tree is 54 degrees
Now here we used the trigonometry
![tan \theta = \frac{Height}{distance} \\\\tan 54^{\circ} = \frac{height}{10}](https://tex.z-dn.net/?f=tan%20%5Ctheta%20%3D%20%5Cfrac%7BHeight%7D%7Bdistance%7D%20%5C%5C%5C%5Ctan%2054%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7Bheight%7D%7B10%7D)
So, the height is
= 10 × 1.38
= 13.8 meters
hence, the height of the tree to the nearest tenth of a meter is 13.8 meters
The answer of the unknown value is 90%
