If we name from up to down the points on the right side : A (summit), B, C, D (summit of right angle), what is x ? ;-)
I was just wondering how one would calculate the length of x on the diagram above. The questions after this in my work are easier so I think I must be missing something easy here as well.
it's not tan 50 100/x is it...?
Any help would be brill, thank you.
