Suppose one angle is x and the other angle is 14x. Supplementary angles add to 180o, so
x+14x = 180
15x = 180
x = 180/15
x = 12.
The required angle is 12o.
Check: The second angle will be 14*12 = 168. 168+12 = 180, so the large angle is the supplement of the small one.

Not by itself. Fourteen (14) is a number (noun) or a numeral (determiner or adjective used with nouns). In the construction "he jumped fourteen times" the term "fourteen times" becomes an adverbial, in the same sense as the adverbs twice or thrice.
an angle that is 54 degrees less than 4 times its complement
Suppose the supplement of the angle is x degrees. Then the angle is 180 - x degrees. Therefore the complement of the angle is 90 - (180 - x) degrees = x - 90 degrees. So 5*(x - 90) - 2*x = 40 Solve the above equation for x.
The angles are 157.5 degrees and 22.5 degrees
