A restaurant offers three types of meats: chicken, beef, and pork. The waiters surveyed 50 customers at random
about their favorite type of meat. The results are listed in
the table and on the graph below. If the restaurant
orders 400 pieces of meat, how many pieces should be
chicken?

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
