Answer:
b. 63
Step-by-step explanation:
A Parallelogram is known to be a flat shape quadrilateral which has four opposite sides Each two opposite sides are parallel and are equal in length. The opposite angles are equal.
The above answer is correct because opposite angles of a parallelogram are equal:
m∠CDA = m∠ABC
where m∠CDA = 63
∴ m∠ABC = 63 (answer)
The 1st choice, the third and the fifth are correct
because 26/9 = 3
and 12/4 = 3
and 21/7 = 3
first most important effect is the erosion and the second most important effect is weathering.
No, because it is not per second. You would have to simplify to per one second for it to be a unit rate. Hope it helps! :)
