Answer:
x = 145
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360
35+x+35+x = 360
2x+70 = 360
Subtract 70 from each side
2x+70-70 = 360-70
2x = 290
Divide by 2
2x/2 =290/2
x=145
(145+145+35+35=360)
This question is very simple to answer if you remember that all parallelograms have two pairs of equal and opposite angles, and that the four angles in any quadrilateral must add up to 360 degrees.
