Answer
m$\angle$A=36$^{\circ}$
m$\angle$B=36$^{\circ}$
m$\angle$C=108$^{\circ}$
Work Step by Step
m$\angle$C=3m$\angle$A
m$\angle$A=m$\angle$B
m$\angle$A+m$\angle$B+m$\angle$C=180
m$\angle$+m$\angle$A+3m$\angle$=180
5m$\angle$A=180
m$\angle$A=36$^{\circ}$
m$\angle$B=36$^{\circ}$
m$\angle$C=3m$\angle$A=108$^{\circ}$
