Answer:
20
Step-by-step explanation:
The angles are vertical angles which means they are equal
60 = 2x+20
Subtract 20 from each side
60-20 = 2x+20-20
40 =2x
Divide by 2
40/2 = 2x/2
20 =x

Answer:
B:81
C:99
D:81
Step-by-step explanation:
In a parallelogram, opposite angles are congruent and consecutive angles (angles next to each other) are supplementary, or add to 180. Considering that there is no diagram, we can use our imagination here. So B is next to A, so <A+<B=180. <B must equal 81. I repeated this process for the rest of the angle measures.
The answer to the question is 96
What you use is y=-3x+-4. I hope that helps.
