By the Law of Sine,

Solve for x and get x = 65.7.
Answer:
2118 dollars
Step-by-step explanation:
His capital gain is the difference in the (sell - buy) prices multiplied by the number of shares (120).
120 * (85.89 - 68.24) = 120 * 17.65 = 2118
The capital gain is a short term gain (held under a year)
The amount is 2118 dollars.
Im pretty sure it's 17.5 since 35 is odd.
(p-8-m)/(-1+p)=1 1/9;p=1 7/8
(p+1)/(p+8+m)=1 1/9;p=1 7/8
1/(8+m)=10/9;p=15/8
that's as far as it can be solved
