Explanation Given: The rafter is raised 9 ft. Procedure used: To compute the unknown sides of a 30 ° , 60 ° and 90 ° triangle if one side is known. 1. Identify the known side of the triangle. 2. If the known side is opposite to the angle 30 ° , then use the below formula to obtain the height and the hypotenuse. Hypotenuse = 2 x Height = x 3 Where, x is the measure of the opposite side of the angle 30 ° . 3. If either the hypotenuse or height is known, use the appropriate formula and solve x and use this x and obtain the remaining sides. Calculation: Let the length of the rafter be z ft.. Redraw the given figure as shown below in Figure 1. From Figure 1, the total length of the rafter is the hypotenuse of the right triangle. Since the sum of the angles in a triangle should be equal to 180°, the unknown angle will be 180 ° − ( 90 ° + 30 ° ) = 60 °
