Similar right triangles
solve for x include a explanation

x = 12

Step-by-step explanation:

The figure in the question was split into the triangles in the attachment to the solution.

Now applying the principle of similar triangles, we have:

cross-multiplying, we have:

solving for x,

x = 12

The mean is the average.

Add them all together and divide by how many numbers there are.

The total is 296.

There are 5 numbers in total.

Therefore you need to divide 296 by 5.

Answer is 59.2!
