15x = 3x + 120 (subtract both sides by 3x)
12x = 120 (divide both sides by 12)
x = 100

What is the value of x for which m || n? x = 40 x = 5 x = 105 x = 30

QveST [7]

Answer:

(A) x=40

Step-by-step explanation:

Given: It is given that m is parallel to n.

To find: The value of x.

Proof: It is given that m is parallel to n, from the figure it can be seen that 105° and (3x-15)° forms alternate exterior angles which are equal in measure because m is parallel to n.

Thus, $105^{\circ}=3x-15^{\circ}$

⇒ $105^{\circ}+15^{\circ}=3x$

⇒ $120^{\circ}=3x$

⇒ $\frac{120}{3}=x$

⇒ $x=40$

Thus, the value of x is 40, hence option A is correct.
