Draw a right triangle with sides 2,2√3, and 4 units. Label all angle measures and sides. Using the side relationships from the f
igure, show that the following trigonometric identities hold true for either one of the non-right angles: a.) tan 0= sin 0/cos 0
b.) sin2 (0) + cos2 (0) = 1,
where 0 represents whichever angle you chose.
