Question

The length of two sides of a triangle are 4cm and 6cm.Between what two measures should the length of the third side fall?

Answer 1

* the answer is = √52

Answer 2

"According to cosine theorem, you can consider side AB = 4, BC = 6.

The side AC is sqrt (AB^2+BC^2–2AB*BC*cosine

The angle between BC and AB is 180 and 0 respectively.

Then we will get many triangles, so we need to modify the angle between BC and A.

Finally, we get the value of third side that range from 2 to 10.
