Find the equation of a line that passes through (-3,10) and is perpendicular to y = 3. a) y = 10 b) y = 3x + 19 c) x = -3 d) y = -3x + 9

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?
