    trig quadrants

    hi. i'd like to see if i got some questions right here.

    i need to find the quadrant for 13pi/14 and write down the related number.
    would this be 13*180/14=167 and in quadrant 2?

    if this is correct how do i find 109pi/4?

    thanks.

    but if i do 109*180/4 it would equal 4905.

    that isn't an angle?

    4905=(360 x 13)+ 225

    This angle is 225 degree so its in quadrant 3 .
