1. state value of these below when a right angle have a AD = opposite side of 3, then the side of AC = hypotenuse is 3 and the side of DC = adjecent is 4

find : sin C, cos C, tan C and sin A, cos A, tan a

2. evaluate each of the following and give your correct answer to 2 d.p. : a. sin 35 degrees + cos 25 degrees b. 2 cos 45 degrees + 3 tan 20 degrees c. 6 sin 55 degrees - 4 cos 15 degrees d. tan 75 degrees - 3 sin 30 degrees

3. calculate this values: a. sin P = 0.532 b. cos Q = 0.363 c. tan R = 0.275 d. sin S = 0.428
