according to question
Angle a= 100°
by linear pair
180°-100°=angle b
so, angle b= 80°
by interior opposite angle
angle c= 80°
Angle a= 100°
by linear pair
180°-100°=angle b
so, angle b= 80°
by interior opposite angle
angle c= 80°

Answer:
ANGLE C IS 80 DEGRESS
Step-by-step explanation:
line l II line m and line n is transversal
therefore, angle a + angle b =180 -(angles in linear pair)
a=100
so, b = 80
line l II line m and line n is tranversal
angle b = angle c -(alternate angle theorem)
angle c = 80
