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

kobusy [5.1K]

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

Answer:

x = 28.07°

Step-by-step explanation:

Recall: SOH CAH TOA

Reference angle given = x°

Opposite = 8

Hypotenuse = 17

Apply SOH:

$Sin x = \frac{Opp}{Hyp}$

Substitute

$Sin x = \frac{8}{17}$

$x = sin^{-1}(\frac{8}{17})$

x = 28.07° (nearest hundredth)
