what the fuck (math gurus)
 

i'm so tired i cannot think straight.

if you have the aspect ratio and diagonal length.. whats the formula to figure out the height/width of a tv/monitor screen?

ok you divide the diagonal measurement by the square root of the sum of the squares of your two ratio figures.
multiply the answer by each ratio figure to get the actual measurements.

eg ratio is 4:3, diagonal is 50"

(4*4)+(3*3)=25
sq root of 25=5
50/5 =10
so screen size is (4*10) by (3*10)


i think

correct formula
