Answer: 7
Step-by-step explanation:
For L to be parallel to M, ( 7x + 9 ) must be equal to ( 8x + 2 ) because the two angles are corresponding to each other.
Equate both equation. That is,
7x + 9 = 8x + 2
Collect the like terms
7x - 8x = 2 - 9
- x = - 7
The minus sign will cancel out
X = 7
Therefore, the value of x that will make L||M is 7
