Answer:
top one is 48 cm, bottom one is 17.5in.
Step-by-step explanation:
From what I understand, these shapes are increasing in size, so they will increase at a certain number. Our top one is rotated, but the 12cm is equivalent to the 3cm from the previous rectangle, thus making it greater by 4 times. To find x, we multiply 12cm by 4 to get 48cm. Same concept for the shapes on the bottom. Our 56in is equivalent to 8in, making it 7 times larger. Now, we multiply 2.5 by 7 to get 17.5in.
Answer:
12i because we have the square root of -144, so we have 144 times -1, and we square root 144 to get 12, and the square root of -1 is i, so we have 12i.

Step-by-step explanation:
Since m∠B = m∠D because alternate interiors angles are congruent when the lines are parallel
and m∠BMA = m∠CMC because vertical angles are congruent
and it AM = MC because it is given that M is the midpoint of AC, then
ΔBMA is congruent to ΔDMC.
Therefore, BM = DM because corresponding parts of congruent triangles are congruent.
Now, M is the midpoint of BD because BM = DM
