Chaire bought just enough fencing to enclose either a rectangle garden or a triangular garden, as shown. The two gardens have the same perimeter. How many feet of fencing did she buy?

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°

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu
