Question 257221
Let x = one angle, y = second angle. Supplementary angles add to 180, so
(i) {{{X + Y = 180}}}
From the given, we can say X = Y + 15. So we have
(ii) {{{Y + 15 + Y = 180}}}
solving for y, we get
(iii) {{{2Y + 15 = 180}}}
(iv) {{{2Y = 165}}}
(vi) {{{Y = 82.5}}}
This means that X = 97.5 and Y = 82.5.
Together they add to 180.
