Quadrilateral upper A upper B upper C upper D is drawn within a circle such that all vertices touch the edge of the circle.
The m∠B
is 93°, mBC
is 58°, and mCD
is 106°. Find the missing angle measures.
(2 points)
m∠A=
°, m∠C=
°, and m∠D=
°
m∠A = 360° - m∠B - mBC - mCD = 360° - 93° - 58° - 106° = 103°
m∠C = mBC = 58°
m∠D = 360° - mCD = 360° - 106° = 254°
Therefore,
m∠A = 103°
m∠C = 58°
m∠D = 254°
