I can't 'slove' a question either. Neither do I know anyone who can, since 'slove' is undefined in the domain of mathematics. I cannot solve your question for an entirely different reason. Namely, you failed to provide the entirety of the given parameters and/or a diagram to illustrate the question. When you re-post this with all of the information required, be careful about capitalization. V and v are NOT the same thing.
