Question

Find the value of x.

Answer 1

x = 64

Explanation:

We know that,

If lines are parallel, the alternate angles are also equal.

Therefore,

`\sf2x = 128`

Now, let us solve for x.

For that, divide both sides by 2.

`x = 64`

Answer 2

64 = x

Explanation:

The angles are alternate interior angles and alternate interior angles are equal when the lines are parallel

128 = 2x

Divide each side by 2

128/2 = 2x/2

64 = x
