A painter has finished painting 45% of a really long fence. If she has painted 90 feet so far, how long is the entire fence?

2nd one in the first row is correct

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°

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
