Feeding and observing sharks has become a popular attraction at water parks. The floor of a newly constructed shark pool in the shape of a parallelogram has sides that measure 25 ft and 61 ft. To meet the minimum required length for the shortest diagonal, the angles must be 77degrees and 103degrees. Find the lengths of the diagonals of the pool. Round the lengths to the nearest foot.

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
