Answer:
16 inches
Step-by-step explanation:
You can separate the screen with a diagonal into 2 right triangles.
The diagonal (hypotenuse) is 19. The base is 10. We need to find the width.
We can apply the pythagorean theorem to this. a^2+b^2=c^2
10^2+b^2=19^2
100+b^2=361
b^2=261
b=16, rounded to the nearest inch.
Therefore, the width of the screen is 16 inches.
