The equation for the line of best fit is f(x) ≈ 1.8x − 5.4 for the set of values in the table. using the equation for the line of best fit, what is a good approximation for x when f(x) = 30?

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°
