Answer:
27.7 in
Step-by-step explanation:
Since the face of the monitor is a rectangle, the diagonal, length and width form a right triangle.
Let d = length of the diagonal
Using the Pythagorean theorem we have
[tex]25^{2} + 12^{2} = d^{2}[/tex]
625 + 144 = [tex]d^{2}[/tex]
769 = [tex]d^{2}[/tex]
d = [tex]\sqrt{769} = 27.7[/tex] in
