Answer:
He loses 7 pounds per week
Step-by-step explanation:
After 3 weeks he weighs 188 pounds.
After 6 weeks he weighs 167 pounds.
Weight loss = (188 - 167) pounds = 21 pounds
Time interval = 6 weeks - 3 weeks = 3 weeks
Rate of change = Weight loss ÷ time interval = pounds per week = 7 pounds loss per week.

Check the picture below.
we know the lines are angle bisectors, so the line makes twin angles, so the line FP is making twin angles, we also know the angle FZP and the angle FYP are right-angles, as well as FP is a common hypotenuse to two right triangles, thus by the HA postulate for right triangles, triangle FPZ and triangle FPY are both congruent, so their sides are also congruents, thus PY = PZ.
