A certain television is advised as a 37-inch tv (the diagonal length).if the width of the tv is 12 inches, how many inches tall is the tv

The TV is 35 inches tall
Step-by-step explanation:
Diagonal(D) is 37 inches, height (H) is X inches s,Width(W) is 12 inches
D^2 = H^2 + W^2
37^2 = X^2 + 12^2
(HEIGHT) X ^2 =37^2-12^2
(HEIGHT)X ^2=1369-144
(HEIGHT) X ^2=1225
(HEIGHT)X=35
So the TV is 35 inches tall
