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

There are 360 degrees to a full circle. You are given 2 angles. 145 and 72 degrees. This equals 217. The remaining angle Y is equal to 360-217 = 143.
