Question

1. Draw a right triangle with sides 4, 4√3 , and 8 units. Label all angle measures and sides. Using the side relationships from the figure, show that the following trigonometric identities hold true for either one of the non-right angles:

a.) tan Ө = sin Ө/cos Ө
b.) sin^2(Ө) + cos^2(Ө) = 1

Edit: Added the missing length value. Still extremely confused as to what to do.
