Answer: 10/x</h3>
This is because
tan(angle) = opposite/adjacent
For the reference angle 38, we have 10 as the opposite side and x as the adjacent side.
Therefore, tan(38) = opposite/adjacent = 10/x
Side note: if you solve for x, you should get roughly x = 12.799
Answer:
15/100 this is the fraction for 15%
