It would be the third answer choice. m<1= 60, m<2= 30, and m<3= 60
The hexagon is split equally, making all the triangles there equilateral, and their angles equal all 60 degrees. That automatically makes angle one and three 60 degrees. For angle two, there is a line, splitting the triangle in half. There are two ways to consider this:
1. Think about the 30°, 60°, 90° special triangles.
or
2. divide 60° by 2, and having 30° in return.
