Answer:The opposite sides are parallel.
They have four right angles.
Step-by-step explanation: I know it because we all learn it in 5 grade.
You can get the different results for the same equation if one of the results is a variable. This is because, in this problem, x=12.
Integral of 2sin(2x) is -cos(2x)
from 0 to pi/2 (sub pi/2 minus sub 0 for x) and then solve
= -cos(2*pi/2)-(-cos0)
= -cos pi + cos 0
= 1 + 1
= 2
W equals 7 :) you’re welcome
