Solve by Graphing x=4cos(35 degrees )

Problem

x=4*cos(35)

Solution

1. Identify the components of the expression, where x is the product of the scalar 4 and the cosine of the angle 35

2. Determine the value of cos(35) using a calculator or a trigonometric table, ensuring the mode is set to degrees.

3. Substitute the approximate value cos(35)≈0.81915 into the equation.

4. Multiply the scalar 4 by 0.81915 to find the value of x

5. Calculate the final product 4×0.81915=3.2766

Final Answer

x=3.2766
