Question 990518
Find the slopes of both lines.
{{{m[1]=1/3}}}
{{{m[2]=1/2}}}
Then the angle is found using this formula,
{{{tan(theta)=abs((m[1]-m[2])/(1+m[1]m[2]))}}}
{{{tan(theta)=abs((1/3-1/2)/(1+(1/3)(1/2)))}}}
{{{tan(theta)=abs((2/6-3/6)/(1+1/6))}}}
{{{tan(theta)=abs((-1/6)/(7/6))}}}
{{{tan(theta)=1/7}}}
{{{theta=8.13}}}{{{degrees}}}
