Align the triangle with one side horizontal, and draw a line up to the top point. Then with the angles you have solved, you can calculate the height of the triangle.<br /><br />Give SK19https://www.blogger.com/profile/17228027233405770851noreply@blogger.comtag:blogger.com,1999:blog-5639270444406781623.post-77806590289907472622010-09-01T23:56:27.827-07:002010-09-01T23:56:27.827-07:00Hi.

The triangles dont have symmetrical values either.<br /><br />i.e. sides A=310, B=420, C=600<br /><br />Hope you can help me.
