Answer:
x = 34
Step-by-step explanation:
The sum of the three angles is 180 since they make a straight line
x+12 + 100 +x = 180
Combine like terms
2x+112=180
Subtract 112 from each side
2x+112-112= 180-112
2x = 68
Divide by 2
2x/2 =68/2
x = 34
Answer:
4 cm
Step-by-step explanation:
Perimeter of a parallelogram is 2b+2h=30 where b is base and h is height.
if AD is 3cm more than twice AB, then it's 3+2x where x is length of AB.
Input this into the perimeter equation: 2(3+2x)+2(x)=30
Simplify to get 6+6x=30
x=24/6=4
Answer is 4 cm.
Subtract x and mutiply v and add the answer
