What is the height, x, of the equilateral triangle?
e-lub [12.9K]

Using the Pythagorean Theorem, the height of the equilateral triangle is given by:

A. h = 7\sqrt{3} inches.

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, according to the following equation:

h^2 = l_1^2 + l_2^2

For this problem, we have that:

  • The height is one side of the triangle.
  • The other side is half the length, of 7 in.
  • The hypotenuse is the length, of 14 in.

Hence the height is found as follows:

h^2 + 7^2 = 14^2

h = \sqrt{147}

h = \sqrt{49 \times 3}

h = 7\sqrt{3} inches.

Thomas buys a cardboard sheet that is 8 by 12 inches. Let x be the side length of each cutout. Create an equation for the volume
Alekssandra [29.7K]
Answer: Your equation would be y = x(12 - 2x)(8 - 2x).

The volume of a rectangular prism is V = LWH. The initial length and width are given as 12 and 8, however that makes the height 0.

If we cut out the corners, they would be the length of x. When we cut out the corners, we are subtract the length x from both ends of the length and width.

So now our measurements are:
Length: 12 - 2x
Side: 8 - 2x
Height: x

Multiply them altogether and you have your equation. Then, you can use your equation to find any measurements that you need.
