If the area of an equilateral triangle is 9root3 cm square find its side​

Mathematics

kobusy [5.1K]2 years ago

Answer:

6 cms.

Step-by-step explanation:

If the side of an equilateral triangle is 2x cm then its height is  √3x and its base is 2x.

Area = 1/2 * base * height

9√3 = 1/2 * 2x * √3x    

9√3 = x * √3x

9 = x^2

x = 3

So length of each side = 2*3 = 6.

x = 9

Find the missing side of the right triangle
o-na [289]

Answer:

<h2>1</h2>

Step-by-step explanation:

Use the Pythagorean theorem:

leg^2+leg^2=hypotenuse^2

We have

leg=3,\ leg=x,\ hypotenuse=\sqrt{10}

Substitute:

3^2+x^2=(\sqrt{10})^2

9+x^2=10             <em>subtract 9 from both sides</em>

9-9+x^2=10-9

x^2=1\to x=\sqrt1\\\\x=1
