Answer:
22.5
Step-by-step explanation:
A dilation is a non rigid transformation which shrink or stretch a figure.
If the scale factor, b>1, the figure will grow
If the scale factor is less than 1, the figure will shrink
The scale factor is 1.5 so the figure will grow.
A dilation about a scale factor makes both figures porportional assuming we know all corresponding angles are congruent. So this means we just multiply PQ by 1.5 to get P'Q'
