The dot product is a technique that solves the resultant vector through the use of matrices. Since we have no coordinates, we can't use matrices. However, we can still solve the resultant vector (red line) through cosine law. The solution is as follows:
R² = 4² + (1/2)² - 2(4)(1/2)(cos π/4)
R = √13.42
R = 3.66
The resultant vector has a magnitude of 3.66.

Answer:
∠ ACB = 128° and ∠ABC = 32°
Step-by-step explanation:
∠ ADC = ∠ CAD (base angles theorem)
∠ ACD = 82° (angles in a triangle add to 180°)
∠ ACB = 128° (angles around a point add to 360°)
∠ ABC = 32° (angles in a triangle add to 180°)
