The tangents from the same point are equal. Each point of the triangle extend 2 tangents to the circle.
Tangents from the uppest point: 8+8=16
Tangents from the lowest point: 4+4=8
Tangents from the third point:
10-4=6
6+6=12
Perimeter: 16+8+12=36units

Since we know what time Dennis' sister finished babysitting, we can calculate how much money she's made since 9p.m. Between 9 and 11 is 2 hours, so we know she made $16 ($8 per hour x 2 hours).
That means she made $22 before 9p.m. ($32 total - $16 made past 9p.m.)
So, you just need to figure out how many hours $22 is worth and subtract that number of hours from 9p.m. That will get you to the starting point of babysitting.
$22 / $5.50 = 4 so we know that $22 is 4 hours' worth of babysitting.
9p.m. - 4 hours is 5p.m., so we know that Dennis' sister started babysitting at 5p.m.
