Explanation:
15. x = 148°, z = 32°
In a parallelogram, adjacent angles are supplementary, so must add to 180°. That also means opposite angles are congruent.
___
17. x = 8, y = -3
The diagonals bisect each other, so ...
2x -4 = 12
x = (12 +4)/2 = 8
and ...
y +10 = 7
y = 7 -10 = -3
__
21. The diagonals of a parallelogram bisect each other, so their point of intersection is their midpoint. The midpoint of WY can be computed as ...
P = (W+Y)/2 = ((-3, 5) +(3, 1))/2 = (0, 6)/2 = (0, 3)
The diagonals intersect at (0, 3).

Answer:
= 6
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Here a = 6 and r = 30 ÷ 6 = 5, thus
= 6
