Let A be the bounded region enclosed by the graphs of f(x) = x , g(x) = x 3 . Find the volume of the solid obtained by rotating the region A about the line x + 5 = 0 .

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

this cant be answered without the graph. you may need to add it.
