If you mean:0 = 800 - 10x + 25 * 20 = 800-10x+25*210x = 800+50x = 8,50 = 800 - 10x + 25 * x * 20 = 800 - 10x + 50x-800 = 40x-50 = x
Always remember that a quadrilateral's (in this case, a parallelogram's) 4 angles must have a sum of 360 degrees. A quadrilateral has a pair of congruent angles. In this case, if a quadrilateral had 2 sides that have 75 degrees, the other 2 must be congruent, and the sum of all 4 angles must be 360.Let x = 1 of the remaining 2 angles (it doesn't matter which one, because they have the same measure)2x + (75+75) = 3602x + 150 = 3602x = 210x = 105The other angles are both 105 degrees.
