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
the answer choice is m∠B=95.5,mADC=84.5 degrees, or m∠D=169 written response only please
To find the measure of angle B, we can use the fact that the sum of angles in a quadrilateral is always 360 degrees. So,
m∠B = 360 - (m∠A + m∠C + m∠D)
m∠B = 360 - (54 + 115 + 86)
m∠B = 360 - 255
m∠B = 105 degrees
Therefore, the true statement is that m∠B=105 degrees.
