If line c is parallel to line d, the measure of angle 9 should be the same as angle 11 according to the Corresponding angles postulate. I<span>f a transversal (line b in this case) intersects two lines (lines c and d) and the corresponding angles are congruent, then the lines are parallel.
So now since the m</span>∠11 is 120 and m∠11 is congruent to m∠9 then we can solve for x.
m∠9 = 6x
m∠11 = 120
<span>
6x = 120
Divide both sides by 6 to get x.
6x/6 = 120/6
x = 20
The answer is then A. </span>
Answer:
1 and 1/2
Step-by-step explanation:
The answer would be <span> because you are using 12 as the base and 12 x 12 = 144 but hoped this helped :) :D :)</span>
Answer:

Step-by-step explanation:
Let A1 be the area of one square and A2 be the area of second square
So,
A1 = s^2
where s is side of square

So side of one square is 
To calculate the length of fence we need to find the perimeter of the square
So,
P1 = 4 * s

For second square:

The perimeter will be:

So the total fence will be: P1+P2
