Solve the given triangle (numerical answers only, round to one decimal place, if needed). A = 49.2° b = 13.2 B = [B] a = [a] c = [c]

Find the values in degrees, rounded to the nearest tenth. (Numerical answer only, no units.) sec-1 (4.5) = [a1] cot-1 (0.54) = [a2]

Find the value of cos (tan-1 u)

Choose all of the following that are true. (Note, they don’t have to match your formula sheet exactly to be true, look for rearrangements like you would when working with identities.)

Match the pairs that make an identity. (Not all options on the right will be used. Note, answers are worth 4 points each.)   1. [d1] 2. [d2] 3. [d3]

Fill in the blank (numerical answers only) 2 sin 10 cos 10 = sin [a1] cos 12 sin 53 – sin 12 cos 53 = cos [a2] tan (32) = cot [a3]
