Question 627598
well, an equilateral triangle is one in which all sides are the same length, so we can find the height by cutting it in half and finding the hypontenuse,  you know, a^2+b^2=c^2

so, it will be 10^2+ 5^2 = c^2

100+25= 125   so lets get the square root of 125, which is 11.18


sooooo, your triangle height will be 11.18 cm
