Ответ:
2 possible solutions
Step-by-step explanation:
First we need to construct the three different triangles, shown in the image.
After we put the equations for each triangle:
Triangle 1:
Triangle 2:
Triangle 3:
As all are quadratic equations, so we resolve them with the general formula for quadratic equations, then we have 6 numerical solutions, but we can only consider those that are positive and real.
For triangle 1:
For triangle 2:
For triangle 3:
So, with the previous results, the only ones that are possible to construct a triangle are:
Triangle 1: because is positive
Triangle 2: because is positive
Triangle 3: None as both are imaginary
