A 30 inch TV set has a width of 24 inches. What is its height?
324 divided by sqrt is 18?
Yep! 18 is correct.
Thank you
You're welcome.
To find the height of a 30 inch TV set with a width of 24 inches, we can use the concept of aspect ratio. The aspect ratio of a TV is the ratio of its width to its height.
In this case, we have the width of the TV, which is 24 inches, but we need to find the height. Let's assume the height is denoted by H.
The aspect ratio is typically expressed as a ratio in the form A:B, where A is the width and B is the height. In this case, the aspect ratio is 24:H.
To solve for H, we need to find the ratio of the given width to the unknown height. We set up the following proportion:
24 inches / H = 30 inches / 1
To solve for H, we can cross-multiply:
24 inches * 1 = 30 inches * H
Simplifying the equation:
24 = 30H
To isolate H, divide both sides of the equation by 30:
H = 24 / 30
H = 0.8
Therefore, the height of the 30 inch TV set is 0.8 inches.
Use this formula for finding the height and width of a triangle when you know the hypotenuse. Let a = the height.
a^2 + b^2 = c^2
a^2 + 24^2 = 30^2
a^2 + 576 = 900
a^2 = 324
a = ?
