Question

Given n equilateral triangle with a side length of 8, find the altitute.

Answer 1

Answer:

$x=4\sqrt{3}$

Step-by-step explanation:

So you have an equilateral triangle, all sides are congruent.

The altitude bisects the base. You have two right triangles with sides x and 4 and a hypotenuse of 8.

64 - 16 = 48

$x=\sqrt{48}$

$x=4\sqrt{3}$

Answer 2

Answer:

6.9

Step-by-step explanation:

8² = 4² + x²

64 = 16 + x²

48 = x²

x = 6.9
