The distance between the Norman and the Voyager is 1,632 yards
Step-by-step explanation:
Let
C > the measure of the angle between the Norman and the Gladstone
c > the distance between the Norman and the Gladstone
a > the distance between the Norman and the Voyager
A> the measure of the angle between the Norman and the Voyager
step 1
Find the measure of angle C
Remember that the sum of the interior angles of a triangle must be equal to 180 degrees
so
38°+57°+C=180°
95°+C=180°
C=180°-95°=85°
step 2
Find the distance between the Norman and the Voyager
Applying the law of sines
c/sin(C)=a/sin(A)
we have
C=85°
A=38°
c=2,640 yd
substitute and solve for a
2,640/sin(85°)=a/sin(38°)
a=2,640(sin(38°))/sin(85°)
a=1,632 yd
