1. Karen is flying a kite on a windy day. Her kite is 80 feet above the ground and her string is 100 feet long. Karen is holding the kite 3 feet above the ground. Find the horizontal distance from Karen to the projection of the kite on the ground. Also, use a guess & check method to find Karen's angle of elevation as she looks up at the kite. Be sure to document and explain how you found the angle.

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
