3. In the figure below, what is m_1 if m27 = 60°? * (1 Point)
O 60°
O 90°
O 120°
O 150°
Pls help

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
