Ned mows a 450 square foot garden in 15 minutes. how many square feet of the garden does he mow in one minutes?
a. 3 square feet
b. 30 square feet
c.435 square feet
d.465 square feet

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°

the answer is 5/14.

hope this .
