Hi, there--
.
You can use the Pythagorean Equation to solve this problem.
.
The height, width and diagonal of the television set form a right triangle. The width and height are the legs of the triangle. The diagonal is the hypotenuse.
.
Let a be the width of the triangle.
Let b be the height of the triangle.
Let c be the hypotenuse of the triangle
.
Substitute the values you know (a=28 and c=35) in the Pythagorean Equation.
.

.
Simplify and solve for b.

.
Find the square root of both sides of the equation. The square root of b-squared is b.

.
In the context of this problem, b=21 means that the height of the television is 21 inches.
.
Hope this helps. Feel free to email me if you have questions about this solution.
