Only answer circle questions use the provided

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?

In triangle abc, angle c is a right angle. find the value of the trig function indicated. find tan a if c = 17 and a = 8

Who can me with this algebra for your guys.
