Answer:
Length of the base of the moniter be 15.59 in .
Step-by-step explanation:
By using the pythagorean theorem.
Hypotenuse² = Perpendicular² + Base²
As figure given in the question.
Hypotenuse = 18 in
Base = 9 in
Putting the values in the formula
Hypotenuse² = Perpendicular² + Base²
18² = 9² + Base²
324 - 81 = Base²
243 = Base²
[tex]Base = \sqrt{243}[/tex]
Base = 15.59 in (Approx)
Therefore the length of the base of the moniter be 15.59 in .
