Triangle PQR with side p across from angle P, side q across from angle Q, and side r across from angle R HELP PLEASE I COULDN'T FIND THE ANSWER ANYWHERE

If ∠R measures 18°, q equals 9.5, and p equals 6.0, then which length can be found using the Law of Cosines?

1. p

2. q

3. RQ

4. PQ

Select the correct answer from each drop-down menu. rewrite the formula to find voltage. the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. the formula to find v is , and the voltage at which the heater operates is volts.
