Question

What is the height of an equilateral triangle with side lengths of 14?

Answer 1

So it's length would be half of the length of the base
`(14)/(2)` = 7 =>
`7^(2)` +
`x^(2)` =
`14^(2)` => 49 + = 196 => x^2 = 147 => x = sqrt 147 = 7 * sqrt 3 . So the altitude is equal to 7 * sqrt 3. An approximate value to that would be 12.12

Hope this helps
