Question

the length of an altitude of an equilateral triangle of side a is
​

Answer 1

Answer:

altitude =3^1/2/2a its right answer

Answer 2

Answer:

altitude of any equilateral triangle = h = √(3⁄2) × s

Step-by-step explanation:

• For an equilateral triangle , all sides are equal to 60°.
• Altitude Of An Equilateral Triangle Formula
• So, sin 60° = h/AS
• We know, AS = AC/2 or s/2 (since all sides are equal)
• ∴ sin 60° = [h/(s/2)]

⇒ Altitude of an equilateral triangle = h = √(3⁄2) × s
