Answer:

i think 180 degrees is the right answer

Angle A = x + 20

Angle B = x

Therefore, x + x + 20 = 180 (as given in question)

= 2x + 20 = 180

= 2x = 180 -20 (Transposing 20 from LHS to RHS)

= 2x = 160

x = [tex]\frac{160}{2}[/tex] ( Transposing 2 from LHS to RHS)

= 80

Answer : Angle A = 80 degrees

               Angle B = 80 + 20 = 100 degrees
