Answer ASAPPP!! I need it by 9 pm!

Answer 1

use sum of angles theorem to find angle B


use SINE law to find BC

52m. BC
——— = ———-
sin(30). sin45

BC = 73.5 m (rounded)

use SINE law again to find AB

AB. 52
_____ = _____
sin105. sin30

AB = 100.5 m (rounded)

Answer 2

BC = 10, AC= approximately 13.66 OR 5+5 √3
