Parallelograms have 2 pairs of congruent, parallel sides, and opposite angles that are congruent.
If side KL = 31, then its opposite side, side MN, must also be 31.
If angle N = 119 degrees, then its opposite angle, angle L must also be 119 degrees.
Angle L and Angle K are on the same side of the parallelogram, which means that they are supplementary angles (add up to 180).
119 + K = 180
Angle K = 61 degrees
Hope this helps!
The quadratic formula solves for X so u can plot it on a graph. it solves for X by subtracting and another way by Adding so you get 2 x's
Answer:
Neither
Step-by-step explanation:
This function isn't even, because
Basically this mean for every x opposites the y value should be the same.
Here, 6 and -6 doesn't share the same y value, nor as -3,and 3.
This function isn't odd because
Basically, this means our y values should be reflected about the orgin,
here, the y values does not switch signs for every x value and it's opposite itself , so this function isn't odd.
So The answer is neither
90 degrees

Step-by-step explanation:
h = -490t² + 1470t
When h = 980:
980 = -490t² + 1470t
Simplifying:
0 = -490t² + 1470t - 980
0 = t² - 3t + 2
Factoring:
0 = (t - 1) (t - 2)
t = 1, 2
There are two solutions because the rocket first reaches the height of 980 cm as it's going up at 1 second, then it reaches that height again as it's coming down at 2 seconds.
