I supposed that is a "n".
Steps as below:
Answer:
252 in²
Step-by-step explanation:
The figure can be considered as a rectangle with the rectangle on the right to be added on and the rectangle on the left to be subtracted.
Area of rectangle with length 12 and width 15 + 6 = 21 is
A = length × width = 12 × 21 = 252 in²
Since the areas of the 2 rectangles to be added / subtracted are equal
both 6 × 3 = 18 in² , then they can be ignored
Then area of figure = 252 in²
Answer: d. alternate interior angles
Note how the two angles are inside, or interior, of the lines L1 and L2. For me, I tend to think of such lines like train tracks. So that takes care of the "interior" portion.
As for the "alternate" portion, we can see that the angles are on either side of the transversal line T.
So that's why angles 3 and 6 are alternate interior angles.
If L1 and L2 are parallel, then angle 3 = angle 6.
