A30 inch tv has an aspect ratio of 4: 3. a tv that is 4 feet wide and 3 feet tall has a diagonal length of 5 ft. how can you use this information to figure out the width of the 30 inch tv? explain.

The answer to your question is  diagonal = 30 in, width = 24 in, height = 18 in.

Step-by-step explanation:

- From the data given, we conclude that the proportion 4:3 is 0.75.

So the 30-inch television must have the same proportion 4:3 or 0.75.

The dimensions of the new TV must be lower than 30.

Use proportion to solve this problem

                               5 : 4 ::  30 : x

                              x = (30 x 4) / 5

                              x = 24 in

And

                             5 : 3 ::  30 : x

                              x = (3 x 30) / 5

                              x = 18

The data given help to calculate the dimensions of the 30 in TV.
