                                          TRIGONOMETRY                                                                  Concepts : Angles and sides 1.      What is the ratio of the sides of a 30 0 , 60 0 , 90 0 triangle ? If the length of the side opposite to  30 0 angle is 10 cm,  how much are the other sides ? 2.      What is the ratio of the sides of a 45 0 , 45 0 , 90 0  triangle ? If the length of the side opposite to. 45 0 angle is  6cm,  find the lengths of the other side. 3.      If the height of an equilateral triangle is 12cm , how much is its side ? 4.      The diagonal of a square is 10cm. What is the length of a side ? Find the area of the square. 5.      The angle between the ground and the stay wire from the top of an electric post is 30 0 . If the distance between the foot of the post and the bottom of the wire is 6 meters, draw a rough figure. Find the height of the post and the length of the stay wire.
