Answer:
130 degrees
Since angles A and D are supplementary (meaning that they add up to 180), we can set up the equation:
180 = 50 + D
D = 130
50º
Explanation:
Angle D & B are vertical angles, meaning they are equal in measure.
So if Angle B = 50º, then Angle D must also be 50º.
Hope this helps! Have a great day!
