Svet_ta [14]

After a thorough research, there exists the same question that has the following choices.

A. 6.29
<span>B. 12.57
</span><span>C. 18.86
</span><span>D. 25.13</span>

The correct answer is letter B 12. 57
First, we need to get the circumference
C = 2*pi*r
C = 12 pi
360/ 60+60 = 360/120 = 3
12 pi / 3 = 4 pi = 4 x 3.1415 = 12.57

What is the perimeter of an equilateral triangle that has a height of 24m?

meriva

Answer:

The perimeter of an equilateral triangle that has a height of 24m is

Option C : 48 square root 3

Step-by-step explanation:

Given:

Height of the triangle =24 m

To Find:

The perimeter of an equilateral triangle = ?

Solution:

Perimeter of the equilateral triangle = 3a

where a is the side of the triangle

Here the height is given as 24 m

Then from the figure

$Sin(60^{\circ}) = \frac{opposite}{hypotenuse}$

$Sin(60^{\circ}) = \frac{24}{x}$

$x = \frac{24}{Sin(30^{\circ})}$

$x= \frac{24}{\frac{\sqrt{3}}{2}}$

$x = \frac{24 \times2}{\sqrt{3}}$

$x = \frac{48}{\sqrt{3}}$

Now

The perimeter is

=> 3x

=> $3 \times \frac{48}{\sqrt{3}}$ -------------------------(1)

Now we know that 3 = $\sqrt{3} \times \sqrt{3}$ --------------------(2)

Substituting (2) in (1)

=> $(\sqrt{3} \times \sqrt{3}) \times \frac{48}{\sqrt{3}}$

=> $48\sqrt{3}$
