Triangle ABC is translated to triangle A'B'C' by the transformation rule as shown below. (*, y) (x+3y-4)
What will be the coordinates of A'?
O (5, 1)
O (8-2)
O (1-2)
O(-1, 1)

step-by-step explanation:

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°
