If m < R+=+124°, what is m < AFD?
m < R+=+124°, measure of its opposite angle is same, so m ∠ D+=+124°
triangle AFD lies between parallel lines, so sides AF+and FD are equal in length
since m <D+=+124° and+AF=FD, measure of angles at A+and D in triangle AFD are 180-124=56°
so,
m<AFD=180-%2856%2B56%29
m<AFD=180-112
m<AFD=68°
