This is about angles. Please answer someone?

Actually, this is not about angles.  It's about the length of the sides in a right triangle.

In EVERY right triangle, the squares of the lengths of the short sides add up
to the square of the length of the longest side.  You're in high school math,so
I'm SURE you've heard that in class before ... possibly even just before you
were assigned this problem.

Let's say that again:  The squares of the lengths of the sides that meet at
the  right angle add up to the square of the length of the longest side.  In
the triangle in this particular problem, that means
                                                                             a² + b² = c²

You know the lengths of 'b' and 'c', so you shouldn't have any trouble finding
the length of 'a'.

Independent variables must be the amount of cans you buy of cat food. The dependent variable, well that must be the cost. Depending on how many cans you buy, the cost changes! :)

HERE'S HOW TO DO IT :)

A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles.

<u>To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.</u>

<u>(SEE EXAMPLE ATTACHED)</u>

<u>HERES WHAT WE KNOW ABOUT COMPOSITE FIGURES:</u>

<u>Composite Figures. A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). For example, figure ABCD is a composite figure as it consists of two basic figures</u>
