cosC = 
= 
( multiply both sides by a )
b - x = acosC ( subtract b from both sides )
- x = acosC - b ( multiply through by - 1 )
x = b - acosC

So first you’ll combine the J’s.
8j - 9j = 1j
+ -5j
Which will be -4j.
That makes: 6 + -4j - 3
So you can subtract 6-3 to make 3.
Which makes 3 + -4j
That’s the answer!
