2. Do the following on paper (or your tablet) scan and upload in this assignment: a. Using a straight edge, draw a 45° 45°-90° right triangle. Be sure in your drawing it is clear to see that the legs are the same length. Don't forget the square in the corner of the right angle. Label the side lengths, choosing 1 unit for the shortest side(s). b. convert 45° to radian measure and label your triangle for part (a) convert 90° to radian measure and label your triangle for part (a) c. Draw a chart as shown, filling in exact values. Practice using our SOH CAH TOA mnemonic and the triangle you created for part (a) to find the exact values and complete the chart. cos(x) X 45° sin(x) tan(x)
