Answer:
x = 2
Step-by-step explanation:

Answer:
a.
b.
Step-by-step explanation:
We are given that


a.Substitute z=0
...(1)
..(2)
Subtract equation (1) from equation (2)


Substitute y=0 in equation(1)

The point (6,0,0) lie on a line.

Let 



Therefore, the vector 
Line is parallel to vector a' and passing through the point (6,0,0).
The parametric equation is given by

Using the formula
The parametric equation is given by

Angle between two plane

and 

Using the formula



Where
in degree.
