What is the length of a rectangle with width 12 in. and area 102 in 2 squared? The length is in
(Simplify your answer. Type an integer or a decimal.)

8.5

Step-by-step explanation:

102 / 12 = 8.5

ok then what happened.

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°
