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}

78 divided by 190 <br><br>steps
Goryan [66]
78 x 100 = 7800 

<span>How many times does 190 go into 780? </span>
<span>≈ 4....190 x 4 = 760 </span>

<span>780 - 760 = 20...bring down the extra 0 to make it 200. </span>

<span>How many times does 190 go into 200? </span>
<span>≈ 1...subtract 190 from 200 to get a remainder of 10 </span>

<span>190 ÷ 7800 ≈ 41</span>

Hope I Helped You!!! :-)
