Idon't know how to do this! can someone me?

The scale factor is 15/6

The posters width is 12 inches

The picture is 40 inches long and 35 inches wide. I know this because I multiplied 16 and 14 by 2.5, which is the scale factor

your answer would be 12

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°
