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

$\sin(10) = \frac{h}{200}$

Make h the subject

h = 200 * sin(10)

Evaluate the product

h = 35 meters

Hence, the height of the tree is 35 meters

If a pentagon is regular, then all of the sides are the same length. This means that

$5x-4=2x+11 \iff 5x-2x = 11+4 \iff 3x=15 \iff x = 5$

So, if $x=5$ , the lengths of the sides evaluate to

$5x-4 = 25-4=21,\quad 2x+11=10+11=21$

So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.
