Fencing encloses a rectangular backyard that measures 200 feet by 800 feet. a blueprint of the backyard is drawn on the coordinate plane so that the rectangle has vertices (0,0) (0,40) (10,40) and (10,0).

a circular flower garden is dug to be exactly in the center of the backyard, with a radius of 60 feet.

what is the equation of the flower garden represented on the blueprint?

(x _ _)^2 + (y _ _)^2 = _

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
