Question

Find the value of x for which m is parallel to n
A) 10
B) 12
C) 40
D) 52

Answer 1

Answer:
`x=5\textdegree`

Step-by-step explanation:

Since we have given that

line m and line n are parallel to each other,

So,

Corresponding angles are equal , as shown in the figure ,

According to question,

`19x\textdegree=180\textdegree-17x\textdegree\\\\19x\textdegree+17x\textdegree=180\\\\36x\textdegree=180\textdegree\\\\x=(180)/(36)\\\\x=5\textdegree`

Hence,
`x=5\textdegree`
