Question

in the given figure ab is the diameter and adc =2bdc if bcd=70 degree then find the angle made by ac at the center of circle

Answer 1

ALL POINTS IN A GEOMETRY FIGURE, AND ALL POINTS USED AS ANGLES, ARE SUPPOSED TO BE CAPITAL LETTERS IN GEOMETRY.

 

The given figure has not been given to us. So you ought to describe it, by mentioning chords, diameters, etc. and various angle measurements.
