Read Solution (Total 1)
-
- given,incircle radius =6cm and circumcircle radius =15cm
therefore height of traingle is =15+6=21
angle between adjacent side and opposite side is 90 degrees
sin 45=21/hypotenuse
hypotenuse=21*sqrt(2)
therfore sides are 21,21,21*sqrt(2) - 9 years agoHelpfull: Yes(0) No(9)
