Although you will see this kind of language used frequently, it has no meaning.

If one angle has measure x and the other has measure "5 times smaller than x", then the measure of the second angle is x, minus 5 times x, which is equal to -4x.

The measure of an angle formed by intersecting lines can't be negative.

And now that I read the problem more carefully, the statement of the problem is flawed in another way: two parallel lines don't form any angles....

Mathematics is "the exact science"; ambiguous or even meaningless language has no place in math.

Resubmit the problem with it stated correctly.

Or, if you have shown the problem exactly as it was given to you, then there is nothing you can do with it.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Sure, this formulation is incorrect.

The meaningful formulation might be this:

    One of the two same side angles at two parallel lines and a transverse is one fifth of the other one. Find all angles.



Then the equation is 

x + %281%2F5%29%2Ax = 180 degs

%286%2F5%29%2Ax = 180  ====>  x = %28180%2A5%29%2F6%29 = 150 degs.


Answer.  One angle is 150 degs, the other is 30 degs.
