ABC is a right triangle with mB=90 . D is a point on [AB] and E is a
point on [BC] .If m(BAE)=m(EAC) , m(BCD)=m(DCA) , |AE|=3 cm , |CD|=4
cm then find |AC|

Dear Nick and other Hyacinthists ... u = angle(BAE); b = AC Clearly AE = b cos(u)/cos(u/2) = 3; CD = b sin(u)/cos(45-u/2) = 4 Hence, if p = cos(u/2); q =...
