Question 1079680
<pre>
Draw this picture:

{{{drawing(200,100,-.5,2,-.5,1.5,line(-3,0,3,0),line(0,-3,0,3), line(0,0,1.5,1),line(1.5,0,1.5,1),locate(.4,.3,theta), locate(1.53,.62,y),locate(.77,0.05,x),locate(.75,.85,r) )}}}

{{{r*tan(theta)/sec(theta)=2}}}

{{{r*tan(theta)=2sec(theta)}}}

{{{r*expr((opposite)/(adjacent))=2*expr(hypotenuse/(adjacent))}}}

{{{r*expr(y/x)=2*expr(r/x)}}}

Multiply both sides by x

{{{r*y=2*r}}}

Divide both sides by r

{{{y=2}}}
