For 7a., angle P is equal the measure of the major arc minus the measure of the minor arc The major arc is 150 and the minor is 80. 150 - 80 = 70, so angle P is 70 degrees. For 7b., the formula we will use is
`PQ^2=PR(PR+RS)`. Filling in accordingly, we have
`PQ^2=4(4+5)` and
`PQ^2=36`. That means that PQ = 6
