1. The sides of a right triangle are in the ratio 3:4:5, as shown. Name and evaluate the six trigonometric functions of angle 0. sin 0 = COs 0 = 4 tan 0 = cot 0 = 3 csc 0 = seco = 2. Two trees stand opposite one another, at points A and B, on opposite banks of a river. A 100 ft C B Distance AC along one bank is perpendicular to BA, and is measured to be 100 feet. Angle ACB is measured to be 79. How far apart are the trees; that is, what is the width w of the river? Use the secondary trigonometric ratio to solve the problem. 3. Solve the right triangle ABC given that side c = 25 cm and side b = 24 cm. B c = 25 a A b = 24 C
