Question

A tree stands on horizontal ground. The angle of elevation of the top of the tree from a point 50 m away from the base of the tree is 11.3°. Calculate the height of the tree.​

Answer 1

Answer: 9.99m

Step-by-step explanation:

So you have a right triangle, and from that you should be able to get all three angles because you have the 90 degree angle, the 11.3 angle, and the mystery angle, so you do the equation 180 (the total amount of degrees for a triangle) - 90 - 11.3, which gives you 78.7, then calculate the rest from there. (You can calculate from only having one side and three angles)
