To do the first question, simplify the equation, putting like terms together, by adding and subtracting to do this.

Then looking at the equation that you solved for, look and see if there are any other equations that are related in some way to the original solved equation.

Pay close attention to the positive and negative signs.

If a tree 41.8 feet tall casts a shadow that is 27 feet long, find the height of a tree casting a shadow that is 18.3 feet long

Neko [114]

Answer:

28.3 feet

Step-by-step explanation:

Given a tree 41.8 feet tall casts a shadow that is 27 feet long

So the Tangent of the angle of the sahdow remains the same for the both trees.

We know that $Tanx=\frac{height of the tree}{length of the shadow}$

$\frac{height of the tree1}{length of the shadow1} = \frac{height of the tree2}{length of the shadow2}$

$\frac{41.8}{27} =\frac{x}{18.3}$

$x=\frac{41.8}{27}\times18.3 =28.3$

Therefore the height of the tree is 28.3 feet
