Answer
m$\angle$A=63$^{\circ}$
m$\angle$B=117$^{\circ}$
m$\angle$C=63$^{\circ}$
m$\angle$D=117$^{\circ}$
Work Step by Step
m$\angle$A=m$\angle$C
2x+3=3x-27
x=30
m$\angle$A=2x+3
m$\angle$A=2(30)+3
m$\angle$A=m$\angle$C=63$^{\circ}$
m$\angle$B=180-m$\angle$A
m$\angle$B=180-63
m$\angle$B=m$\angle$D=117$^{\circ}$
