The zip line forms a right triangle with the tree, when elevated
The height of the tree is 35 meters
<h3>How to calculate the height of the tree</h3>
Represent the height of the tree with h.
So, the height h is calculated using the following sine function

Make h the subject
h = 200 * sin(10)
Evaluate the product
h = 35 meters
Hence, the height of the tree is 35 meters

Answer:
what is the question about the given numbers
The last one is correct because 60+35+35+35=165
55+55+55=165
Sinα=h/L where h=height, L=string length...
h=Lsinα so
h(25°)=50sin25≈21.1ft
h(45°)=50sin45≈35.4ft
