Answer:
Step-by-step explanation:
a = 180 - 2(19) = 142°
b = 90° Triangle in a circle with one side as a diameter makes right triangle
c = 2(19) = 38°
d = 38°
e = 38°
f = 19° alternate angle
g = 19° equilateral triangle
h = 90 - 19 = 71°

Step-by-step explanation:
It may or may not be the correct answer. I'm only trying to help.
A = c/sin C, and b by the proportion b/sin B = c/sin C.
a/sin 37° = 4380/sin 109°
a sin 109° = 4380 sin 37°
a = 4380 sin 37°/sin 109° ≈ 2787.8
b/sin 34° = 4380/sin 109°
b sin 109° = 4380 sin 34°
b = 4380 sin 34°/sin 109° ≈ 2590.4
Sin(pi/6) would be appropriate as that is 1/2
