1 gallon is 8 pints. So 14 pints would be more than 1 gallon. 2 pints make 1 quart and it takes 4 quarts for a gallon. 14 pints is 7 quarts which is more than 1 gallon. 1 gallon is not greater than 14 pints.
Use the Law of Sines to find side x.<span>
x / sin(A) = c / sin(C)</span><span>
x / sin(61°) = 15 / sin(81°)</span><span>
x = (sin(61°) x 15) / sin(81°)</span><span>
x = <span>13.283
Or rounded to 13.3
