15 √ 2

Step-by-step explanation:

Equilateral triangles have three equal side lengths, three equal angles of 60 degrees, and three equal altitudes.

You would think that the height of an equilateral triangle would also be equal to it's sides, but it's not. The formula for height is: side/2 x √3

10√6 / 2 * √ 3 = 15 √ 2

The decimal form: 21.2

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
