To solve for cos(65 degrees), you can use a scientific calculator or refer to a trigonometric table.
If using a calculator, make sure it is in degree mode. Then, enter "cos(65)" into the calculator and press the "=" button. The calculator will give you the result, which is approximately 0.42262.
If using a trigonometric table, find the row that corresponds to 65 degrees and look for the cosine value in that row. The table will tell you that cos(65 degrees) is approximately 0.42262.
Remember to always check whether your calculator or table is set to use degrees instead of radians. This is important because trigonometric functions like cosine have different values depending on the unit of measurement.
