Dara's computer monitor is 20 inches wide and 12 inches high. Which measurement is closest to the length of the diagonal of Dara's monitor? A) 15 inches

B) 16 inches

C) 23 inches

D) 32 inches

C) 23

Step-by-step explanation:

If the computer monitor is 20 inches wide, and 12 inches high, we can solve for the diagonal by using the Pythagorean theorem.

Let a = the width, let b= the height, let c = the diagonal.

a^2 + b^2 = c^2

20^2 +12^2 =c^2

400 + 144 = c^2

544 = c^2

C is approximately equal to 23 inches.
