    but the angle is coming 25 instead of 15? please explain

    eduncle-logo-app

    15 how?

    eduncle-logo-app

    yes. because it's coming 25 when i am calculating

    eduncle-logo-app

    90-(65+10)

    eduncle-logo-app

    but the dip is 35 from S towards E. so that will be 55 na instead of 65?

    eduncle-logo-app

    65 is the not the dip it's the azimuthal strike direction

    eduncle-logo-app

    To be honest, I am not getting this sum clearly. why are you taking azimuthal strike direction? I am getting confused. Can you please explain in another way

    eduncle-logo-app

    ok

    eduncle-logo-app

    eduncle-logo-app
