Assuming PQRS is a parallelogram, we have PQ = RS, and angles S and R are supplementary so their measures sum to 180°.
So
5<em>x</em> = <em>x</em> + 12
4<em>x</em> = 12
<em>x</em> = 3
→ PQ = 5<em>x</em> = 15
and
12<em>z </em>° + 6<em>z</em> ° = 180°
18<em>z</em> ° = 180°
<em>z</em> = 180/18 = 10
→ m∠<em>S</em> = 12•10° = 120°
S = 14-3 (s being sandras age)
If the center of dilation is A, this means that point A is invariant.
- This means you can eliminate C and D.
Also, the scale factor is 3/4, which means that A'C' is more than half the length of AC.
- This is best reflected by option B
