Solve for x cos(52)=19/x

Problem

cos(52)=19/x

Solution

1. Multiply both sides of the equation by x to move the variable out of the denominator.

x*cos(52)=19

2. Divide both sides by cos(52) to isolate x

x=19/cos(52)

3. Evaluate the cosine of 52 using a calculator.

cos(52)≈0.615661

4. Calculate the final value by dividing 19 by the decimal value.

x≈30.859

Final Answer

x=19/cos(52)≈30.859
