Answer:
x=28
Step-by-step explanation:
vertical angles are congruent
3x-12=72
3x=84

Do Area = (base 1 + base2) × H
Answer:
b x =-2/3
Step-by-step explanation:
-3(2x+1) + 3x = 6x + 3
Distribute
-6x -3 +3x =6x+3
Combine like terms
-3x-3 = 6x+3
Add 3x to each side
-3x+3x-3 = 6x+3x+3
-3 = 9x+3
Subtract 3 from each side
-3-3 = 9x+3-3
-6 = 9x
Divide by 9
-6/9 = 9x/9
-2/3 =x
