Explanation:
Sides -
As measure of opposite sides of a parrelelogram are equal -
4a + 10 = 6a
10 = 6a - 4a
10 = 2a
10/2 = a
5 = a
Therefore - WZ = 4 x 5 + 10 = 30
And as, WZ = XY (opposite sides are equal), XY = 30
I don't know how to find the length of ZY and WX
Angles -
As adjecent angles of a parrelelogram are sumplimetory, (b+15) + 2b = 180
So,
B+15 + 2b = 180
3b +15 = 180
3b = 180 - 15
3b = 165
B = 165 / 3
B = 55
Therefore, angle X = 55 + 15 = 70 (b+15)
And angle Y = 2 x 55 = 110 (2b)
And, angle W = angle Y (opposite angles of a parrelelogram are equal)
So, angle W = 110
And, angle Z = angle X (opposite angles of a parrelelogram are equal)
So, angle Z = 70
