The interior angles of a triangle add up to 180
180 - 97 - 34 = 49
150 / Sin 34 = b / Sin 49
multiply both sides by Sin 49
(Sin (49)* 150) / Sin 34 = b
b = 270.39 feet
-7.14 should be your answer!
The answer is 5 7/8
b/c 2 1/2 = 2 4/8
so then convert 8 3/8 as an improper fraction which is 67/8
and do the same w/ 2 4/8 which is 20/8
the do: 67/8 - 20/8 = 47/8
simplify 47/8 = 5 7/8.
Your answer is 5 7/8 inches of ribbon left.
