You can make the equilateral triangle into a right triangle by cutting it in half. So, your sides would be 4.5, 9, and x.
Using Pythagorean Theorem, you know that a^2 + b^2 = c^2.
The 'a' would be equal to 9, and 9^2 is equal to 81.
B is equal to 4.5, and 4.5^2 is 20.25.
So, you have the following:
81 + 20.25 = c^2
And that makes 'c' equal to 101.25.
The square root of 101.25 is approximately equal to 10.06.
So now you know the height, 10.06.
There are 7 nickels and 8 dimes, if you look closely at the procedure, you can see how <em>x </em>is established for the nickels (0.05) and <em>y </em>for the dimes (0.10).
The quadratic formula is one of the ways to find a solution to the quadratic equation, alongside graphing and completing the square. The quadratic formula can be represented as
where a is the squared value, b is the multiplied value, and c is the constant.
3x^2 - 10x + 8 = (x - 2)(3x - 4)
