Which property of complex numbers is demonstrated below?
(6 + 7i) + (0+01) = (6+7i)

its 4 because 2 times 2 is 4, if you double the number two you get four

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°

ƒ = 0.03b
