To calculate the width of the TV, we can use the Pythagorean theorem.
Let's denote the width of the TV as x inches.
According to the Pythagorean theorem, the sum of the squares of the width and height should be equal to the square of the diagonal.
So, we have:
x^2 + 30^2 = 57^2
x^2 + 900 = 3249
x^2 = 3249 - 900
x^2 = 2349
Taking the square root of both sides, we get:
x = √2349
x ≈ 48.46
Rounding to the nearest whole inch, the width of the TV is approximately 48 inches.
Use the spaces provided below to calculate the missing measurement for each of the 6
types of screens. You are looking for the width, height, OR the diagonal. You must show
all steps in your work. The size of a screen is given by the length of its diagonal.
Round your answer to the nearest whole inch.
