Answer:
it takes 30 hours for Jamie to equal Lisa's earnings
Step-by-step explanation:
Lisa earns $8.10 an hour and worked 40 hours.
Total amount Lisa earns = rate times hours
Total amount Lisa earns =
Jamie earns $10.80 an hour
LEt 'n' be the number of hours Jamie works
Total amount Jamie earns =

Divide by 10.80 on both sides
n= 30
So it takes 30 hours for Jamie to equal Lisa's earnings

Let's begin noting that a triangle is isosceles if and only if two of its angles are congruent. We can thus find the angle <ABP, recalling that the sum of the interior angles of a triangle is equal to 180°.
Finally, let point K be the intersection between segments BC and PQ, and let's note that the triangle PQB is a right isosceles triangle, since all the angles in a square are equal to 90°, and the two triangles APB and BQC are congruent.
Therefore, the angle BKQ is equal to 180-50-45=85°.
Of course angle BKP=180-85=95°.
Hope this helps :)
