The size of a rectangular television set is the length of one of the diagonals of its screen.

The angle formed by the diagonal of a 42-inch rectangular television set and its width is 28°.

What is the length of the television screen?

Wording of the question is a bit unclear:

  If 'width ' is the height of the screen

then  'length'    would be 42 sin 28    this is the measure across the bottom of the screen

 

If 'width' and 'length' are the same thing then the measure across the bottom of the screen would be 42 cos 28
