The two corners DAC and BAC share a common AC side. What degree can the DAB angle have if the DAC angle is 120 degrees and the BAC angle is 50 degrees?
The AC beam divides the DAB angle into two angles, so the DAB angle is equal to the sum of the DAC and BAC angles:
∠DAB = ∠DAC + BAC;
∠DAB = 120 ° + 50 ° = 170 °.
