    Draw chord BC to get an inscribed quadrilateral ABCD. Angle C should be 75 (one of the equal angles in the isoceles triangle BCD)

    For an inscribed quadrilateral, opposite angles sum up to 180. Hence, x is 180-75 = 105

    105 degrees I guess cyclic quadrilateral will be used.

    Answer: 105, Sorry 150 is by mistake…

    I think it would be 60. Central angle is twice the inscribed opposite angle ! I think we will use this theorem here!

    angle x= 30 degrees

    108….i made it into a regular pentagon since BD equals CD… and interior angle of a pentagon is 108 degrees!

    x=105

    30*2=60
    180-30=150
    150/2=75
    75*2=150
    150+150+60=360
    150+60=210
    210/2=105
