Two observers are standing on a shore 468 m apart at points A and B and measure the angle to a sailboat at a point at the same time. Angle A (observer A) is 120 degrees and angle B (observer B) is 13.4 degrees. Find the distance from observer A to the sailboat.
A) 149 m
B) 132 m
C) 108 m
D) 141 m
Solving Triangle:
A geometrical problem containing a triangular shape can be solved using the Law of Sines and the Law of Cosines. When we particularly solve the scalene triangle, the Law of Sines is highly recommended. This law clearly specifies that sinAa=sinBb=sinCc
