PQR and ABC are supplementary angles and PQR is nine times as large as ABC. Determine the measure of each angle.
-------------------
q + b = 180 degrees
q = 9b
---------------------
Substitute for "q" and solve for "b":
9b + b = 180
10b = 180
b = 18 degrees
---------------
Since q + b = 180
q + 18 = 180
q = 162 degrees
-----------
PQR = 162 degrees
ABC = 18 degrees
