Answer:
11. D. 9
12. G. 9+y x (3 / 4)
13. Either A or C
17. A. Point W
18. J. 32
19. D
2134
Step-by-step explanation:
17.7
angle B = 180 - 81 - 65 = 34 degrees
as the sum of all angles in any triangle is always 180 degrees.
a/sin(A) = b/sin(B) = c/sin(C)
the sides are always on the opposite side of the angle.
so,
10/sin(34) = AB/sin(81)
AB = 10×sin(81) / sin(34) = 17.7
