Question

Knowing that television sets screen size refers to the diagonal of the screen if a 35 in set also has the width of 28 inches what is the height of this set?

Answer 1

We can use the Pythagorean theorem because you're finding the height of a triangle.

a^2 + b^2 = c^2
a^2 + 28^2 = 35^2
a^2 = 1225 - 784
a^2 = 441
a = ?

Answer 2

Take the square root of 441. If its a decimal round it to the nearest !0ths place.
