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.
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.)
