Angle ADB = 47° , angle XBC = 82° , angle BAD = ???pls help as fast as u can |

Answer» o the figure We will use two PROPERTIES of a cyclic QUADRILATERAL :(1) Sum of the angle measures of OPPOSITE angles = 180 degree.(2) Angles subtended by a chord any where on the circumference in the same segment are equal to each other.comforted degree:Let the required angle BAC = θ degree._______________________________As it is clear from the figure, both the angles ABC and BDC are the angles subtended by chord BC on the circumference in the major segment. degree:HENCE —Angle BAC = θ = BDCAngle XBC + Angle ABC = 180 degreeanglere:=> Angle ABC = (180–89) = 91 degree.=> Angle ADC = 180 - 91 = 89 degree=> 47 + θ = 89 degree=> θ = 89–47 = 42 degree |
