The angle’s measure is 60 degrees more than triple that of its supplement. Fine this angle.
-----------
A = the angle
S = the supplement
---
A + S = 180 degs
A = 3S + 60

Can you do the rest?

supplementary angles are two angles whose sum is 180°
let one angle be alpha and its supplement beta
so, alpha%2Bbeta=180° ........eq.1
if measure of alpha is 60° more than triple that of its supplement beta, we have
alpha=3beta%2B60°........substitute in eq.1
3beta%2B60%2Bbeta=180° .........solve for beta
4beta=180-60°
4beta=120°
beta=120%2F4°
beta=30°

find alpha

alpha=3beta%2B60°
alpha=3%2A30%2B60°
alpha=150°
