Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).

Given right triangle abc, what is the value of tan(a)?
