Langkah Penyelesaian

Evaluate trigonometric functions in the problem

$$0.2125565616700221 + 0.7812856265067173 + 1.2799416321930788 + \tan(60) 3.0776835371752527$$

Tambahkan 0.2125565616700221 dan 0.7812856265067173 untuk dapatkan 0.9938421881767394.

$$0.9938421881767394+1.2799416321930788+3.0776835371752527\tan(60)$$

Tambahkan 0.9938421881767394 dan 1.2799416321930788 untuk dapatkan 2.2737838203698182.

$$2.2737838203698182+3.0776835371752527\tan(60)$$

Dapatkan nilai \tan(60) daripada nilai trigonometric.

$$2.2737838203698182+3.0776835371752527\sqrt{3}$$
