Answer:
x = 22°
y = 26°
z = 48°
Step-by-step explanation:
∠PQS and ∠QSR is a pair of alternate interior angles
plus PQ is parallel to SR
then
x = 22°
SPR is an isosceles triangle then m∠PRS = 66°
Therefore x + y = 180-(66+66) = 180-132 = 48
then y = 48 - x = 48-22 = 26
finally, z = x + y = 48

Explanation:
In the second step, I multiplied both sides by r to move it to the left side. Then I divided both sides by p to isolate r.
In short, the r and p swap places.
The residuals are the difference between the dataset values and the values computed from the regression formula. Here is a plot.
