Students were asked to find the difference between the positions of two sea creatures. An octopus was positioned at 180 feet below sea level. A narwhal was swimming 7 feet below sea level. Demarcus said you can find the difference with this expression: -7- (-180)

Maria said you can find the difference with this expression: -180 - 7

step-by-step explanation:

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°
