First off, the area of the circle would be 78.54
Now, you would do (area of the triangle)--- AT-78.54=answer
I don't know how to find the area of the triangle with just the circle's radius, so this is all I can do. I'm sorry!
First of all why is there 2 similar equation connected to one another?
Second in order to solve this all you need to do is plug in the number and solve for x
For 485
85x+60=485
85x=420
X=5
Do the same thing and you get 3
It is a right, isosceles triangle.
Answer: Variables
F and C are placeholders for numbers. They are called variables because they are allowed to vary, or change. If you change C then it affects F, and vice versa. If the values for the placeholders is not allowed to change, yet it holds a number, then it is considered a constant. In this case, we don't have constants or else the formula isn't too useful.
