Answer:
[tex]x=4\sqrt{3}[/tex]
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
[tex]x=\sqrt{48}[/tex]
[tex]x=4\sqrt{3}[/tex]
Answer:
6.9
Step-by-step explanation:
8² = 4² + x²
64 = 16 + x²
48 = x²
x = 6.9
