Acomputer moniter is solid by the diagonal length of the screen a computer monitor has a 15 inch screen the screen has a width of 13 inches what is the height of the screen round your answer to the nearest tenth

For this problem, you would use the Pythagorean Theorem (a^2 + b^2 = c^2)

A and B are the length and width of the triangle. The triangle is created by the diagonal line splitting the computer screen. C is the hypotenuse, which is the diagonal line, and will always be the longest side of the triangle. 

When we plug in the numbers into the formula, we would get this:

13^2 + b^2 = 15^2

B is the unknown variable in which we are trying to find.
First, you square 13 and 15:

169 + b^2 = 225

Then, subtract 169 from both sides:

b^2 = 56

Finally, find the square root of both sides:

b = 7.483314774

Simplify to the nearest tenth, and the answer is 7.5
