If the tree is 4 feet tall and it's shadow is 8 feet tall, we can come up with this equation.
4x=8.8, x being what you need to multiply by to get the value.
Simplify the equation, and you have x=2.2.
So, if the flagpole's shadow is 22 feet long we can come up with this equation. 2.2y=22.
simplify that equation and we end up with y=10
So therefore, the height of our flagpole is 10 feet.
I really hope this helps, have an awesome day!!
