PR is tangent to a circle at point P. Q is another point on circle such that PQ is diameter of circle and RQ cuts circle at M. if radius of circle is 4 units and PR=6units. find ratio of triangle PMR to PQR.
Choose one:
A) 11/20
B) 3/5
C) 13/20
D) 18/25
E) 18/26
let PM = y   QM= x   MR = 10-x   In triangle PQM,   PM^2+QM^2 = PQ^2   =&gt; x^2+y^2=64 .....(1)   In triangle PMR,   PM^2+ MR^2= PR^2   y^2+(10-x)^2=36......(2)   solving for x and y   x=6.4   y=4.8   taking permineter of triangle PQR =24   perimeter of triangle PMR = 14.4   take ratio   14.4/24=
