Answer: The value of x is 28.

Step-by-step explanation:

Since line m is parallel to line l.

So, we assume that

(3x+21)° and (4x-7)° are corresponding angles.

And we know that , corresponding angles formed when a transversal cut the  parallel line are equal.

So, they must be equal to each other.

[tex]3x+21=4x-7\\\\21+7=4x-3x\\\\28^\circ=x[/tex]

Hence, the value of x is 28.
