any ideas?
40?
This a right angle (90) so if that one is smaller the answer can't be bigger then 90. |dw:1343098568020:dw|
yes either that or 75

since both are less than 90
40 right?
but if you carefully draw it out, you'll see that it's roughly half of that right angle drawn above
and since 40 is close to 45 (which is half of 90), I'd go with 40 as well
