A special effects engineer is helping create a movie and needs
to add a shadow to a tall totem pole that is next to a 6-foot-tall
man. The totem pole is 48 feet tall and is next to the man, who
has a shadow that is 2.5 feet long.
What is the length of the shadow that the engineer needs to
create for the totem pole?

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
