Question 128080: I don't know where to begin. Can someone help with this word problem?
What does it mean to refer to a 20in TV set or a 25-in TV set? Such units refer to the diagonal of the screen. A 35- in TV set also has a width of 28 inches. What is its height? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A 35- in TV set also has a width of 28 inches. What is its height?
----------------
Use Pythagoras.
You have a right triangle with the diagonal being the hypotenuse.
EQUATION:
35^2 = x^2 + 28^2
x^2 = 35^2-28^2
x^2 = 441
x = sqrt(441)
x = 21 inches.
