To get an A in her math class, Jada needs to have at least 90% of the total number of points possible. The table shows Jada's results before
the final test in the class.
1. Does jada have 90% of the total possible points before the final test? Explain how you know
2. Jada thinks she will at least get 92 out of 100 on the final test, she will get an A in her class. Do you agree?

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.
