21.1 should be the correct answer because 4.5% of 2000 is 90
Answer:
Step-by-step explanation:
r+58
Let r=3
3+58
61
The arrangement forms an isosceles triangle with equal legs of 8 mi. The angle between the legs is,
123-63 = 60°. Therefore, the other two angles ares:
Angles = (180-60)/2 = 120/2 = 60°
It can therefore be noted that all angles are equal and thus the resulting triangle is actual an equilateral triangle and thus all the sides are equal.
It can be concluded that the ships are 8 miles apart.
