supplementary is 180.
let x be first angel
let y be second angel
given that, y = 20+2x (1)
and x + y = 180 (2)
substitute y into eqt (2), we have
x + 20 +2x = 180
3x = 160
x = 53(1/3)
substitute x into eqt (2)
y + 53(1/3) = 180
y = 180 - 53(1/3)
y = 126(2/3)
thats it.

Unfortunately, Yahoo doesn't make it easy to fix such things. You could try e-mailing the correct responder(s) to let them know about the mistake.
