19. In the triangle ABC, the side lengths are BC = 14 and AC = 7. What's the angle measurement of B?
O A. 11.19°
O B. 31.42
O C. 45.61°
O D. 26.57°

You need more information, I will be more specific, there is a book called "Geometry" by Moise Downs where the following theorem is stated on the chapter 7.

Let ΔABC and ΔDEF be two triangles where AB = DE and AC = DF if

∠A > ∠D then BC > EF, which in simple terms means that, if two sides are equal, the angle between them can vary as much as you want and that will directly imply the size of the third size of your triangle.

Therefore, there is information missing in order to solve the question
