Answer:
x+15=5x-41
5x - x = 15 + 41
4x = 56
x= 56/4
X = 14
x+15 = 14 + 15 = 29°
5x - 41 = 5(14)-41 = 70 - 41 = 29°
We consider the unknown angle as " y "
y +29 =180 —> y=180 -29= 151
SO; X = 14 and angle 29° , 29° —> Opposite angles
and other angles 151° , 151° —> Opposite angles
I hope I helped you^_^
