Draw the following diagrams:quadrilateral ABCD inscribed in circle E. The mAB=54 degrees, mBC=115 degrees, and mCD=86 degrees. select the true statement m∠B=95.5,mADC=84.5 degrees, or m∠D=169 written response only please
m∠D = 169
To find m∠D, we can use the fact that the sum of all interior angles of a quadrilateral is equal to 360 degrees.
mAB + mBC + mCD + m∠D = 360
54 + 115 + 86 + m∠D = 360
255 + m∠D = 360
m∠D = 360 - 255
m∠D = 105
Therefore, m∠D is 105, not 169.
