Answer:
the answer would be 217 [degrees]
Step-by-step explanation:
Since m<1 and m<2 are next to each other, they are adjacent. Adjacent angles must share a common side which is m<W. This means they have to be added. m<1+m<2= m<XYZ
145+72=217
= x1 + x2/2 , y1 + y2/2
= 7+-1/2 , 1+(-1)/2
Midpoint = (3,0)
