5. Determine the acute angle formed at the point of intersection created by the following pair of lines: \( L _ { 1 } : ( x , y ) = ( 2,2 ) + s ( - 1,3 ) \) and \( L _ { 2 } : ( x , y ) = ( 5,1 ) + t ( 3,4 )\) 

Answer

\(\cos\theta= \frac{|(- 1,3)\cdot(3,4)|}{|(- 1,3)|\cdot|(3,4)|} = \frac{9}{5\sqrt{10}} \\\Rightarrow \theta= 55.3° \)
