Answer:
110.1°
Step-by-step explanation:
Use the inverse cosine function (arccos or cos⁻¹).
... cos(θ) = -0.344
... θ = arccos(-0.344) = 110.1°
_____
The range of the arcos( ) function is 0 – 180°, so no adjustment of the angle is necessary. (Make sure your calculator is in <em>degrees</em> mode.)
Answer: Transaction 3 = -177.65 and Transaction 4 = -401.40
You subtract the account balance of each transaction from the original account balance (360) to get your transaction amount.
360 - 182.35 = 177.65
360 - (-41.40) = 360 + 41.40 = 401.40

We can then multiply 3 x 2 to get 6 possible arrangements
Step 3: 4x+8=4
Step 4: 4x=4-8 ⇒4x=-4
Answer: Step 4: 4x=-4
Step 5: x=-4/4=1
