Answer:
Let angle POT be a and angle QOR= b
a+b=180°(linear pair)
a= 180-b. (i)
a-b=80° (given)
a= 80+b. (ii)
Equating (i) and (ii)
180-b= 80+b
180-80= b+b
100 = 2b
b= 100/2 = 50°
a= 80+b = 80+50 = 130°

Answer:
a = 130 and b=50
Step-by-step explanation:
Answer:
Let angle POT be a and angle QOR= b
a+b=180°(linear pair)
a= 180-b. (i)
a-b=80° (given)
a= 80+b. (ii)
Equating (i) and (ii)
180-b= 80+b
180-80= b+b
100 = 2b
b= 100/2 = 50°
a= 80+b = 80+50 = 130°
