Question

How do I see this up to solve it? 35/6 = x/5? Or am I mix matching it?

Answer 1

ANSWER

42 feet

EXPLANATION

Let's draw the triangles,

They are both right triangles. The angle in green is the same for both triangles because the shadow is being cast from the same light source. Therefore these two triangles are similar and thus, the ratio between corresponding sides is constant,

$\frac{x}{6ft}=\frac{35ft}{5ft}$

Solving for x,

$x=6ft\cdot\frac{35ft}{5ft}=6ft\cdot7=42ft$

The tree is 42 ft tall.
