The total voltage across the resistors in the circuit is \(V_{total} = 8V + 5V + 5V = 18V\). However, the voltmeter is placed across the 5V and 5V resistors, where the potential difference across them is zero, so the reading on the voltmeter is 0V.

The portion of the line \( 4x + 5y = 20 \) in the first quadrant is trisected by the lines \( L_1 \) and \( L_2 \) passing through the origin. The tangent of an angle between the lines \( L_1 \) and \( L_2 \) is:
