Diagonal of TV = 32 inch
Height of TV = 15.7 inch
The diagonal makes the TV into a right triangle,
Therefore,
Diagonal = hypotenuse = c = 32 inch
Height = perpendicular = a = 15.7 inch
Width = base = b
Using pythagoras theorem

Taking square root on both sides

Rounding off to nearest tenth
b = 27.9 inches
The width of the TV is 27.9 inches
