Never join the two terminals of the electric cell without connecting them through a switch and a device like a bulb. If you do so, the chemicals in the electric cell get used up very fast and the cell stops working. Thus, both the electric cell and the bulb have two terminals each.

Answer 2

Answer:

Let the required angle be x°

Let the required angle be x°its complement = (90 – x)°

Let the required angle be x°its complement = (90 – x)°As per condition, we get
