to find the solution, use the Pythagorean theorem
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
in this problem, you are given a and b. c is always the diagonal.
[tex] {15.5}^{2} + {19.5}^{2} = {c}^{2} [/tex]
now, all you have to do is solve
[tex]240.25 + 380.25 = {c}^{2} [/tex]
[tex]620.5 = {c}^{2} [/tex]
there's no way to simplify this further, so this is your answer
[tex] \sqrt{620.5} = c[/tex]
hope this could help!

The length of the diagonal should be[tex]\sqrt{620.5}[/tex]

Given  that,

  • a television screen measures approximately 15.5 inches high and 19.5 inches wide.

Based on the above information, the calculation is as follows:

[tex]a^2 + b^2 = c^2\\\\15.5^2 + 19.5^2 = c^2\\\\240.25 + 380.25 = c^2\\\\620.5 = c^2\\c = \sqrt{620.5}[/tex]
