Answer:
Resistance of the circuit is 820 Ω
Explanation:
Given:
Two galvanometer resistance are given along with its voltages.
Let the resistance is "R" and the values of voltages be 'V' and 'V1' along with 'G' and 'G1'.
⇒
⇒
Concept to be used:
Conversion of galvanometer into voltmeter.
Let be the resistance of the galvanometer and
the maximum deflection in the galvanometer.
To measure maximum voltage resistance is connected in series .
So,
⇒
We have to find the value of we know that in series circuit current are same.
For For
⇒ equation (i) ⇒
equation (ii)
Equating both the above equations:
⇒
⇒

⇒
The coil resistance of the circuit is 820 Ω .
Angles will probably be 96° 35° and 49°
I tried to explain it with the working out, just re arrange the cosine rule for angles instead of side lengths.
if you need it explaining at all just message me :)
hoped it helped
