Angles 6 and 7, because they are alternate along the transversal.
Also angles 1 and 4.
the construction of fields of formal infinite series in several variables, generalizing the classical notion of formal Laurent series in one variable. Our discussion addresses the field operations for these series (addition, multiplication, and division), the composition, and includes an implicit function theorem.

Answer:
angleB = 41.4°
Step-by-step explanation:
✨ Trigonometry✨
cos theta = adj / hyp
theta = inverse-cos adj / hyp
theta = inverse-cos 12 / 16
theta = inverse-cos .75
theta = 41.4°
*theta is the 0 with a line through it
