so, did you do the construction, and measure BC?
what did you get?
If angle A is 120 then you should get
BC^2 = 7^2 + 9.5^2 - 2*7*9.5*cos120°
BC ≈ 14.3
Construct triangle ABC in which AB is 7cm AC is 9.5cm and is 120.measure BC.

Construct triangle ABC in which AB is 7cm AC is 9.5cm and is 120.measure BC.
The drawing and the calculation that's what I want
Construct ∆ABC such that /AB/=6cm, /AC/=8.5 cm and BAC = 120°
