The angles of a triangle are 50, 60 and 70. A circle touches the sides at P, Q and R. Calculate the angles of triangle PQR.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

if i put something wrong your not gonna like it so rather not say nothing.
