Final answer:
The height of the screen of the television is 20 inches.
Step-by-step explanation:
If you're referring to the physical height of a computer monitor, television, or any display screen, it's typically measured in inches or centimeters. Manufacturers provide this information as part of the specifications for the screen.
To find the height of the screen, we need to use the given information. The height of the screen is one half the width plus 5 inches. The width is given as 30 inches. So we can set up an equation:
Height = 1/2 * Width + 5
Plugging in the value of the width, we have:
Height = 1/2 * 30 + 5
Height = 15 + 5
Height = 20 inches
