Explanation Given: The length of the rafter is 19.5 ft. The angle made by the joist and rafter is 45°. The rafter is over hanged 18 in. Procedure used: To obtain the unknown length of the given right triangle. 1. Identify the known sides and the unknown sides of the triangle and substitute them in the formula Hypotenuse = Leg 2 or x 2 , where x is the length of leg. 2. Solve for the unknown values. 3. Write as an exact values or appropriate value, as desired. Calculation: Compute the length of the joist as follows. Let 2 x be the length of the joists. Consider one part of the given triangle as shown below in Figure 1. From Figure 1, the total length of the rafter is 18 ft 18 in and x is the leg of the right triangle. Since the sum of the angles in a triangle should be equal to 180°, the unknown angle will be 45°. Compute the value of x as follows. Substitute Hypotenuse = 18 ft in Hypotenuse = x 2
