I believe you would need to use the Pythagorean theorem and solve for PR so if you use x for the length of PR the equation would be $$x ^{2}=9^{2}+12^{2}$$ Then I would solve for x.

kpop4life123 · Answer

x^2=9^2+12^2 
     = 81  + 144
81^2

Just wandering.

Should this:  x^2=9^2+12^2 

be

x^2=9^2+14^2  where x = PR

directrix · Answer

Attached is the triangle I see with which the Pythagorean Theorem would be used.
