MCQ
Each side an equilateral triangle is $10\ cm$ long. The height of the triangle is:
- A$10\sqrt{3}\text{cm}$
- ✓$5\sqrt{3}\text{cm}$
- C$10\sqrt{2}\text{cm}$
- D$5\text{cm}$
✓
Answer
Correct option: B.
$5\sqrt{3}\text{cm}$
Height of equilateral triangle $=\frac{\sqrt{3}}{2}\times\text{Side}$
$=\frac{\sqrt{3}}{2}\times10$
$=5\sqrt{3}\text{cm}$
