Alrighty friend, let me explain you a math.

We're gonna want to start by setting up a fraction. We'll set up the fraction as height/shadow. The stick's height is 6 feet and the shadow is 2 feet, making the fraction 6/2. The second fraction only gives us the shadow, so the fraction is x/14.

Now, we're gonna do some cross multiplication m8. 6/2 x x/14. Multiply 6x14 = 84 and 2x (x) = 2x - - - > 2x = 84

Do you some basic algebra here, and divide both sides by 2.

Your final answer is 42, so the tree is 42 feet tall.
