Question

in the adjoining figure AB is a straight line. Find the value of x.​

Answer 1

Answer :

• The value of x = 20

Explanation :

Given that,

• The adjoining figure AB is a straight line

We need to find,

• The value of x

Solution,

Since AB is a straight line the sum of the angles on the

same side should be 180°

∠AOC + ∠COD + ∠DOA = 180°

2x° + 3x° + 4x° = 180°

9x° = 180°

x° = 20°

Therefore,

• The value of x = 20
