Answer:
44°
Step-by-step explanation:
∠ DEB and ∠ AEC are vertical and congruent
Thus ∠ DEB = 58°
The measure of the chord- chord angle DEB is half the sum of the measures of the arcs intersected by the angle and its vertical angle, that is
(DB + AC ) = 58° ( multiply both sides by 2 )
DB + AC = 116°, that is
DB + 72° = 116° ( subtract 72° from both sides )
DB = 44°
The equation takes the x coordinate of the vertex and puts it into an equation in vertex form with the y coordinate and the radius. The radius is entered as its squared value. The general form of a circle is (x-h)^2 + (y-k)^2 = r^2. So yours would look like this: (x-3)^2 + (y+2)^2 = 25
