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)

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

=> $48\sqrt{3}$

Jamie just bought 2 boxes. The first box is square.With each side measuring 10units and is 4 units high.The second box is rectan

Mama L [17]

You are given two boxes. The first box is a square with each side measuring 10units and 4 units high. The second box is a rectangle with a height of 5 units and width of 10 units. If the second box has twice the volume of the second box, then you need to find the volume of the square.

square
V = bh
V = 10(10)(4)
V = 400

Rectangle
V = LWH
2(400) = 10(5)H
H = 16 units
