1. Draw the two special triangles, labeling all angles and sides. Use the "right angle symbol" for right angles. 2. Use the triangle below to write all six trigonometric functions of 0, in the standard order from class. Simplify radicals, rationalize denominators, and reduce fractions. 12 8. 3. Draw a right triangle with this information a = 5, A = 15°. Write your results using the format from the class. Round sides to two decimal places. Make and label a rough sketch of the triangle. %3D 4. A wheelchair ramp is to be constructed from level ground up to a doorway 0.54 meters above to the ground. To comply with ADA regulation, the angle the ramp makes with the ground would be 5.6°. How long will the ramp be? (Round to two decimal places) 5. The foot of a ladder 5m long rest on level ground 2m away from the base of a vertical wall. What angle does the ladder make with the ground, and how far up the wall does it reach? The recommended safe angle is 75. Is this ladder set about right, or is it too steep, or not steep enough? (Round to one decimal place.)
