If a flat- screen TV is a rectangle with a 53-inches diagonal and a width of 45-inches, What isheight of the screen?
Use Pythagorean theorem
a^ + b^2 = c^2
a^2 + 45^2 = 53^2
a = sqrt(53^2-45^2) = 28 inch height
Use Pythagorean theorem
a^ + b^2 = c^2
a^2 + 45^2 = 53^2
a = sqrt(53^2-45^2) = 28 inch height
If a flat- screen TV is a rectangle with a 53-inches diagonal and a width of 45-inches, What isheight of the screen?
\(w^2+ h^2=d^2 \) \( Pythagoras\)
\(h=\sqrt{d^2-w^2}=\sqrt{(53^2-45^2)\ inch^2}=\sqrt{784\ inch^2}\)
\(h=28\ inch\)
\(The \ height \ of \ the \ screen \ is \ 28 \ inch.\)
