Suppose in right triangle ABC, cos(A)=3/7, with the right angle at C. Suppose the length of side AC is 14 units.
(i) Draw a sketch, labeling all vertices.
(ii) Now calculate the lengths of all three sides. Show your work.
(iii) Calculate the angles to the nearest tenth of a degree. Show your work.
(iv) Add all the information from (ii) and (iii) to your sketch.
