What is the altitude of an equilateral triangle whose side is 16 cm? |
3\(\sqrt{3}\) cm 9\(\sqrt{3}\) cm 8\(\sqrt{3}\) cm 7\(\sqrt{3}\) cm |
8\(\sqrt{3}\) cm |
(a = side of an equilateral triangle) Altitude of an eq. triangle = \(\frac{\sqrt{3}}{2}\) × a = \(\frac{\sqrt{3}}{2}\) × 16 = 8\(\sqrt{3}\) cm |
