The scale factor from rectangle abcd to rectangle wxyz is 4. what is the length of side wx?
a) 1.7 m
b) 3.4 m
c) 6.8 m
d) 13.6 m

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°
