You need to add all those numbers together and there your answer !! Good luck !
Subtract the smaller median (30) from the larger (55). The result, 25, is the average improvement in test scores from the pretest score to the posttest score.
∠PXS = (180 - 106) ÷ 2 // isosceles triangle
∠PXS = 37°
∠XQR = 180 - 106 //parallelogram
∠XQR = 74°
∠RXQ = 74° //Isosceles triangle
∠SXR = 180 - 37 - 74 // Adjacent angles on a straight line
∠SXR = 69°

Answer: ∠SXR = 69°

Answer:
f(3) = -1
Step-by-step explanation:

f(3) = -3 + 2
f(3) = -1
