Extracted text: Guy wires attached to a pin, embedded in a foundation exert the forces shown in the below diagram. By use of OBLIQUE TRIANGLES, verify that the resultant force exerted on the foundation is 109.09 N operating at 130.56°. Show all steps to receive full marks. If any method other than oblique triangles is used, or if thought process/steps are not shown, marks will only be awarded for the answer. 140.0 N 70.0 N 20.0° 30.0°
