Β and radius 
is given by 
. From the figure, we know that the radius of arc ADC is 4, but we don't know the measure of the arc. Since there are 360 degrees in a circle, the measure of arc ADC is equal to the measure of the arc formed by 
subtracted from 360. The measure of the arc formed by 
and 
. To find them, we can use basic trigonometry for a right triangle, since by definition, tangents intersect a circle at a right angle.
must then be
