A ladder LA, leans against a vertical pole at a point L which is 9.6 meters above the ground. Another ladder LB 12meters long lean on the other opposite side of the pole and at the same point L. If A and B are 10meters apart and on the same straight line as the foot of the pole calculate, correct to two significant figuresI) the length of the ladder LAII)Angle which LA makes with the ground

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
