A 50-Inch television measures 50 Inches diagonally and has a width of 40 inches. A 30-inch television measures 30 inches diagonally and has a width of 18 Inches. How much taller is the 50-inch television than the 30-inch television?
step 1
Find the height of 50 in TV
applying Pythagorean Theorem
50^2=40^2+h^2
h^2=50^2-40^2
h^2=900
h=30 in
step 2
Find the height of 30 in tv
applying Pythagorean Theorem
30^2=18^2+h^2
h^2=30^2-18^2
h^2=576
h=24 in
step 3
Find the difference
30-24=6 in
answer is 6 inches
