D becaucause you have to do 12x8 and then 12x5 and whatever 12x8 is you but the answer bring down the + and do 12x5
Using an indirect proof:
Assume that the figure is a trapezoid.
All trapezoids are quadrilaterals.
All quadrilaterals' interior angles add up to 360° because any n-gon's interior angles add up to 180(n-2)°.
We are given that the trapezoid has three right angles.
All right angles are 90°, thus these right angles have a total measure of 270°.
We can conclude fourth angle must be 90°.
If it has four right angles, it is a rectangle.
Rectangles have two sets of parallel sides.
However, trapezoids have exactly one set of parallel sides.
Alas, our figure cannot be a trapezoid.
Answer:
Yes
Step-by-step explanation:
The following figures are similar. Similar means they are the same shape with the same angles. They aren't congruent and only similar because they are different sizes. If you dilate the smaller rectangle, you can make the larger one.
Answer:
Amelia is 264 inches
Step-by-step explanation:
do 22 ×12 because at birth she was 22 inches and now she is 12 months.
