Question

Find the height of an equilateral triangle whose
side is 12 V3 cm.​

Answer 1

Answer:

Here, formula is

Height = (√3 × side)/2

So, height = (√3 × 12√3)/2 = 18 cm.

Hope this help you....

Answer 2

Answer:

18 cm

Step-by-step explanation:

Here, the triangle is equilateral so all the sides will be equal and the median will be the height.

Hence,

BD = 12√3cm / 2 = 6√3cm

Now,

We will apply Pythagoras Theorem on the tringle ABD

AB^2 = BD^2 + AD^2

AD^2 = AB^2 - BD^ 2

AD^2 = (12√3)^2 - (6√3)^2

So,

The height is 18cm
