Answer 1

Answer:

The answer is AOC=60 and BOC=120

Explanation:

As they are angles on a straight line, do, 3x+6x=180

=9x=180

=x=$\frac{180}{90}$

=x=20

so 3x=3×20=60

    6x=6×20=120

Answer 2

Answer:

AOC + BOC =180°( linear pair)

3x+6x=180°

9x =180°

x=180/9

x=20°

so,

AOC=3*20=60°

BOC=6*20=120°
