Answer: DBE - 71 degrees, BEF = 161 degrees
Step-by-step explanation:
Angle ABD and Angle DBE are supplementary, which means they add up to 180 degrees.
Therefore, 3x + 4 + 2x + 1 = 180
5x + 5 = 180
5x = 175
x = 35 degrees
So, angle DBE = 2*35 + 1
= 71 degrees
Angle BEF is supplementary to Angle BED = x -16 = 19
19 + angle BEF = 180
Angle BEF = 161 degrees
