I have 2 triangles when joined by a common side form a quadrilateral:
1. right angled triangle with the opposite side about 17 metres
2. non-right angled triangle with one side of about 21 metres.
Joined together their area is about 200m squared.
The adjacent side of the right angled triangle joins the non-right angled triangle so they share a side.
I'm trying to find the length of the shared side and the unknown side of the non-right angled triangle.
I'm thinking something like 200=x+y
Where x is area of right triangle and y is area of non right triangle
I was thinking of Herons rule but I dont have enough information and it would be a lot of working.
