What is the altitude of an equilateral triangle whose side is 14 cm? |
7\(\sqrt{3}\) cm 6\(\sqrt{3}\) cm 4\(\sqrt{3}\) cm 8\(\sqrt{3}\) cm |
7\(\sqrt{3}\) cm |
(a = side of an equilateral triangle) Altitude of an eq. triangle = \(\frac{\sqrt{3}}{2}\) × a = \(\frac{\sqrt{3}}{2}\) × 14 = 7\(\sqrt{3}\) cm |
