Will give brainlist for right answer me

First, you can determine that because the parallelogram has two pairs of equal sides, it also has two pairs of equal angles. Also, a parallelogram’s interior angles add up to 360°. So since two different angle measures are given, their angles must add up to 180° (360°/2). So then you can add both of the expressions of those two angles and put them into an equation and isolate x.

2x - 10 + 2x + 50 = 180°
4x + 40 = 180°
4x = 180° - 40
x = 140°/4
x = 35

Therefore, x is 35.

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
