Question

D, E, & F please

Requires a ruler and a protractor. Fold a standard size sheet of paper in half. This measures 8.50 inches x 5.50 inches. a Convert its size to millimeters 215.9mm x 139.7mm b. Measure the diagonal using a centimeter ruler. Express your answer in mm. 257mm Calculate the length of the diagonal (in mm) using Pythagoras theorem. c. (215.9+139.)-257.2mm Using trigonometry, find the angle θ that the diagonal line forms with the horizontal d. Use a protractor to measure this angle. e. How does your measurement compare with your calculation? Explain what source(s) of error may account for the difference. t :E - Focus- 25 8

Answer 1

The angle theta can be found BD = 257.2 mm or 257 mm AB = 215.9 AD = 139.7 mm Now, tan theta = AD/AB = 139.7/215.9 theta = tan^-1 139.7/215.9 = 32.905 degree tidleequal 32.91 degree you can use now to measure the angle DBA or theta, which should be roughly around 33 degree The difference will give you the error. This error can arise because of folding process. During the folding we may not exactly be fold around the diagonal. There may be slight deviation, which results into the error.
