Step 1
Find the length of each side of the triangle using the distance formula: AB = √[(4-5)^2 + (3-8)^2] = √26 AC = √[(7-5)^2 + (6-8)^2] = √8 BC = √[(7-4)^2 + (6-3)^2] = √18 Show more…

If the vertices $A, B, C$ of a triangle $A B C$ are $(1,2,3),(-1,0,0),(0,1,2)$, respectively, then find $\angle \mathrm{ABC}$. $[\angle \mathrm{ABC}$ is the angle between the vectors $\overline{\mathrm{BA}}$ and $\overline{\mathrm{BC}}]$.
