An 18 in long rebar is driven into the ground until it touches an underground pipe. A backsight to a benchmark with an elevation of 393.66 ft is taken with an automatic level. The backsight has a rod reading of 7.56 ft. A foresight is taken to the rod resting on top of the rebar. The rod reading is 1.01 ft. What is the elevation of the top of the pipe

Aphrase is shown read the phrase and give me the answer

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.
