Find the value of x so that line m is parallel to line n.
a. 57
b. 51
c. 50
d. 49

,C) x =50

Step-by-step explanation:

Given : Parallel line m and n in figure.

To find : Find the value of x

Solution : We  have given

Two parallel line with traversal line

Alternate interior angle property :  The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles are equal.

3x + 11  and angle 161 are alternate angle .

3x + 11 =161.

On subtracting both sides by 11

3x = 161 -11

3x = 150

On dividng both sides by 3

x =50

Therefore,C) x =50

56
