This problem is about ratios.

Solve for X

The tree is 50ft tall.
That equals 4,810. Make sure to have a placeholder when you multiply
The area of the composite figure is 50.8m
I would go with -15 that’s what I came up with
First we have to get x by itself, so we multiply two on each side,
then we get 5x=660/4, I like to simplify here, so I would change it to 5x=165, then we divide each side by 5
x=33
