The number obtained on rationalizing the denominator of 1/(√7--2) is

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°

i think it might be a but you might want a second opinion

i believe that the answer is

b. y-1=-2(x-4)

hope this !
