Finding the length of one side of a triangle
WebIf given one angle of a triangle and two sides, it is possible for two triangles to exist given the same dimensions. For example if told to find the missing sides and angles of a triangle given angle A is 19 degrees, side a is length 45, and side b length 44, you may begin by using the law of sines to find angle B. This is shown below:
