    Stationing question

    I need to find Point A on the following horizontal curve. I can find PC, PT, M, E, etc. But I can't for the life of me figure out how to find the stationing of Point A. I calculated the arc length to be 1151.92 feet (to save time in trying to help me). Any guidance is appreciated. Thanks!
