Question

Find the value of X in the following figure ​

Answer 1

Answer:

x = 60°

Step-by-step explanation:

Given that L and M are parallel lines. We can see that x and 2x are forming co interior angles of parallel lines. Sum of co interior angle is always equal to 180°.

Therefore,

⇒ x + 2x = 180°

⇒ 3x = 180°

⇒ x = 180°/3

⇒ x = 60°

Required value of x is 60°.

Answer 2

Step-by-step explanation:

Since l || m and a similar straight line is forming both the angles.

Their sum should be 180°

Hence-

x + 2x = 180° ( sum of interior angles)

3x = 180°

x = 180/3 = 60°

2x = 2 × 60 = 120°
