Grogg draws the following figure. It so happens that angle SAP is \(178\) degrees less than 4 times angle SOP. Find the degree measure of angle SAP.
Because angle(SAP) and angle(SOP) each has its vertex on the circle and they cut off the
same arc, arc(SP), they must be equal in size.
Let x = angle(SAP) = angle(SOP)
angle(SAP) = 4 · angle(SOP) - 178o
x = 4 · x - 178o
-3x = - 178o
