The nth term of a sequence is 25-3n a) Work out the first three terms of the sequence.
b) Work out the value of the first negative term of the sequence,

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°

really your just stupid if you don't know this
