Answer:

50º

Step-by-step 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!

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
