Using the same formula and the accompanying figure, deduce a formula for the altitude, h, of an equilateral triangle in terms of its side, c.

really need help don't know what it means by "accompanying figure" because there's nothing "accompanying" it!! :/

thank you so much!

....Sorry, the formula is c squared = a squared + b squared

If you know the area of the equilateral triangle,

Area = 1/2 ch

Therefore h = (2c)area

Do you know the area?

If it is a right triangle, you have the Pythagorean Theorem.

a^2 + b^2 = c^2, where c is the hypotenuse.

However, there is no way we can find the "accompanying figure."
