We have been given that Mark had $436.
Further, we are given that Chris has $86 lesser than what mark had.
Let us assume that Chris has $x. Therefore, we can set up an equation:
(Amount Chris had) + $86 = (Amount Mark had)
Upon subtracting 86 from both the sides, we get:
Therefore, the required expression that represent the amount of money that Chris had is .
Since you don't have any angle and its opposite side, you cannot establish the ratio for the law of sines, so you must use the law of cosines.
