Explain why the factor 1.5 is broke. into two numbers in the model.

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?

What is the approximate value of  q  in the equation below? –1.613–1.5220.5853.079
