Why is it important to use parentheses correctly when calculating with trigonometric functions?

• To make the equation look neat

• To ensure the calculator is in degree mode

• To prevent syntax errors

• To avoid calculating the tangent of an incorrect angle

What happens if you forget to close the parentheses when calculating tan(27) * 15?

• You calculate the tangent of a 405-degree angle

• The result is zero

• Base and Height

What should you do if the variable is not alone after cross-multiplying?

• Add a constant to both sides

• Subtract a constant from both sides

• Multiply both sides by the coefficient of the variable

• Divide both sides by the coefficient of the variable
