Question 147078
Supplementary means the angles add up to {{{180}}}degrees
Call the larger angle {{{a}}}
Call the smaller angle {{{180 - a}}}
{{{3*(180 - a) = 2a - 5}}}
{{{540 - 3a = 2a - 5}}}
{{{5a = 545}}}
{{{a = 109}}}
{{{180 - a = 71}}}
The angles are {{{71}}} degrees and {{{109}}} degrees
check:
{{{3*(180 - a) = 2a - 5}}}
{{{3*(180 - 109) = 2*109 - 5}}}
{{{3*71 = 218 - 5}}}
{{{213 = 213}}}
OK
