To calculate: The width and the height of the TV.
Answer to Problem 12CT
The required width and height of the TV are 27.84 inches and 15.66 inches respectively.
Explanation of Solution
Given information:
The ratio of the screen’s width to its height =
Width of the screen = 32 inches
Formula used:
Pythagoras theorem:
For a right-angle
Calculation:
The given ratio of the screen’s width to its height is
Consider the width and height of the TV be
To find the width and height of the TV, use Pythagoras theorem
Substitute 32 for hypotenuse,
Simplify further.
Since, x is a factor of the dimensions of the TV;
So, it cannot be negative
Thus,
Now, the width of the TV is
And, the height of the TV is
Hence, the required width and height of the TV are 27.84 inches and 15.66 inches respectively.
