The television set has a rectangular shape. The diagonal of this rectangle along with its width and length together form a right angular triangle.
This means that we can apply the Pythagorean theorem which states that:
(diagonal)^2 = (length)^2 + (width)^2
Let the width be w. We know that the length is 0.75 times the width, this means that: length = 0.75 w
Substitute in the above equation:
(20)^2 = (0.75w)^2 + (w)^2
400 = 0.5625 w^2 + w^2
400 = 1.5625 w^2
w^2 = 256
w = 16
This means that the width of the screen is 16 in.
First, add 1.4 to the number given.
-3.2 + 1.4 = 1.4 - 3.2 = -2.2
a.-2.2 is one of your answer
Next, subtract 1.4 to the number given
-3.2 - 1.4 = -4.6
a.-4.6 is your next answer
a. -2.2, a. -4.6 are your two answers
