Answer:
PQ = 20
Step-by-step explanation:
Theorem: The length of the median of a trapezoid is the average of the base lengths.

PQ + 12 = 32
PQ = 20
See how easy that is if you know the theorem!
Answer:
both angles are the same, so you can use it interchangeably in proving.
But i suggest you to mantain only one, because it's easier to understand and it looks better.
Answer:
i hated iready xD the answer should be 2
Step-by-step explanation:
if you use ride over run the rise would be 2 and the run is 1
= 2
33 degrees C
Step-by-step explanation:
On the integer scale, the numeric values can be added thus
23 to -10
23 to 0 and 0 to -10
23-0 = 23
0 -(-10) = 10
23 + 10 = 33
Thus, 33 degree C is the difference between the two temperatures.
