Answer:

Yes

Step-by-step explanation:

We know that because AB and CD are parallel,

angles A and D are supplementary
angles B and C are supplementary

As supplements of congruent angles are congruent, this means angle B is congruent to angle C.

Thus, ABCD is a parallelogram because it is a quadrilateral with 2 pairs of opposite congruent angles.

Solve for x 5 (x+2)=8x+20

inessss [21]

Distribute the 5 outside the parentheses into the parentheses.
5(x+2)=8x+20
5x+10=8x+20
Bring x to one side, other numbers to another
5x+10=8x+20
-8x -8x
-10 -10
-3x=10
divide by -3
x=-10/3
approximately -3.33333333
