Question 1204663
*[illustration diagram]
From the diagram, we will use the cosine formula to find the distance between the two ships at 10 hours, i.e., BC.
So, c^2=a^2+b^2-2abcosc
c^2 = 110^2+230^2-2(110)(230)cos125
= 12100+52900+29022.9676=94022.9676.
as c^2 = 94022.9676
c = sqrt(94022.9676) = 306.631 miles, or mi.
