An organization will give a prize to a local artist. the artist will be randomly chosen from among painters, sculptors, and photographers. what is the probability that the artist chosen will be a painter or a photographer? write your answer as a fraction in simplest form.

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°

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
