    80 Degrees
    খ)
    75 Degrees
    গ)
    60 Degrees
    ঘ)
    105 Degrees

    Explanation

    Angle traced by hour hand in 17/2 hrs = (36012×172)o\left(\frac{360}{12}\times\frac{17}2\right)^o = 255 Angle traced by min hand in 30 min =  (36060×30)o\left(\frac{360}{60}\times30\right)^o = 180 Therefore,  Required angle = (255 - 180) = 75o75^o
