An observation tower is to be constructed on top of Quezon Hill 420 m. amsl. A 3.75 m.  tower was constructed at Aurora Hill 507 m. amsl, 30 km. from Quezon Hill. Another 7.00 m. tower was constructed at Mirador Hill 420 m. amsl, 20 km. from Quezon Hill. Compute the height of tower to be constructed at Quezon Hill which is in between Aurora and Mirador Hills so that the three hills will be intervissible.

Electrical Plans

An electrical plan is also known as an electrical drawing or a wiring diagram. It is a kind of visual representation which bears the blueprint symbols of all the electrical components in electrical house plans or various building construction projects. In other words, electrical plans describe electrical circuits and systems that build up the electrical house plans or building plans. An electrical engineer who works on various construction projects creates an electrical drawing. The engineer outlines the electric planning with different symbols and lines forming a detailed electrical circuit. These drawings are a means of representation for the clients, who will carry out the actual wiring process. In a nutshell, an electrical plan showcases the circuitry with the proper placement of electric components.
