Question

Find the value of X, then find AB and DC.
(opposite sides are congruent)
AB= 3x+8
DC= x+12

Answer 1

Answer:

X=2, AB=14, DC=14

Step-by-step explanation:

3x+8=x+12

Subtract x from both sides

2x+8=12

Subtract 8 from both sides

2x=4

Divide by 2 on the sides

Answer: x=2

Then replace the x's with (2) and multiply

3(2)+8 and (2)+12

Answer 2

Answer:

Both AB and DC are equal to 14.
