Supplementary angles add up to 180.
if one angle is alpha and its supplement is beta, then
alpha%2Bbeta=180
if given that alpha is 3 times its supplement, then
alpha=3beta...substitute in alpha%2Bbeta=180
3beta%2Bbeta=180
4beta=180
beta=180%2F4
highlight%28beta=45%29+
=>alpha=3beta=> alpha=3%2A45=>highlight%28alpha=135%29
