8.) a. mPW = 125
     b. mRPW = 27.5
     c. mPRW = 62.5
     d. mWERE = 27.5
     e. mWER = 62.5
     f. mEWR = 27.5

9.) PS =  \sqrt{(AP)^2 - (AS)^2}
PS =  \sqrt{12^2 - 8^2}
PS =  \sqrt{80}
PS = 4 \sqrt{5}

QS = \sqrt{10^2 - 8^2}
QS =  \sqrt{100 - 64}
QS = 36
QS = 6

AB = 16, AP = 12, AQ = 10
PS + QS = PQ

Therefore, the answer is:
PQ = 4 \sqrt{5} + 6
