Question

Find angle AOB and angle BOC if angle AOB=x & angle BOC =x+20​

Answer 1

Answer:

are they complimentary angles, if yes

then x =70

x+20=110

Answer 2

Answer:

Take three angles angle 1 , angle 2, angle 3

Angle 1 = x

Angle 2= x + 20

Angle 3 = y

angle 1 + angle 2+ angle 3 = 180 degree

x + x + 20 + y = 180 degree

2x + 20 + y = 180 degree

180 - 20 - y = 2x

= 160 - y = 2x

= we don't know y

but I don't know answer :(
