Hi everybody,

I was shopping for a new TV and was taken aback when I realised that knowing the hypotenuse and the right angle of a triangle didn't allow me to determine the measurements of the entire thing. My maths skills aren't good enough to come up with the right equation but if you know an angle and a measurement and where that measurement is in relation to the angle, then shouldn't you be able to figure out the intercept points?

Please help me because I'm sure I'm wrong and I want to know why!
