(1-2)sqr + (4+3)sqr = Rsqr
1 + 7sqr = Rsqr
50 = Rsqr
R = 5Root 2
*** sqr = Squared
Always remember that if a line or any shape passes through a point, the equation must be satisfied when you sub that point into that equation. like what i did above
hope it helped
ask me if u have any further questions
