Step 1: According to the given information draw a figure.

            NOTE:  Height of the slide from the ground = 2 m

                        Angle of the slide =   30\degree

                        The length of the slide = ?

                    

  

Step 2:  Use the trigonometric ratio to find the unknown length.

              EXAMPLE:  To find adjacent side(CB) use \sin \theta = \frac{opposite}{hypotenuse}

                            \sin 30\degree = \frac{2}{hypotenuse}

                                     \frac{1}{2} = \frac{2}{AC}

                                   AC = 2 * 2

            Therefore, the length of the slide = 4 cm
