Answer 1

Answer:

WKT,

The Angles are Supplementary.

Hence angle AOB+BOC = 180°

therefore,

60°+3x = 180°

180°-60° = 3x

120° = 3x => x = 120°/3 = 40°ans.

Step-by-step explanation:

Hope it helps you:-)

Answer 2

Answer:

x= 40

Step-by-step explanation:

Since, AOC is a straight line.

therefore, 60 + 3x = 180 (linear Pair)

3x = 180 - 60

3x = 120

x = 120÷ 3

x = 40
