Suppose you live 6.9 miles from a hill. from your home you see a plane directly above the hill . you're angle of the elevation to the plane is 24 degree. what is the planes altitude. choices are a 2.8 miles. b -14.7 miles. c 6.3 miles. d 3.1 miles

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
