Please help Find n(A) for the set, and then circle in one of the bubbles A = {xAx % N and 18 K x K 24} (I'll give brain reward)

Step-by-step explanation:

B.n(A)=7.

good luck to you

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°
