Calculating x.
Notice!
AD = 100 cm.
Therefore;
Area triangle ABD + Area triangle ACD = Area triangle ABC
0.5*2x*100sin60+0.5*x*100sin60 = 0.5*2x*xsin120
100x+50x = x²
x = 100+50
x = 150 cm.
It implies;
AB = 2*x
AB = 2*150
AB = 300 cm.
AC = x
AC = 150 cm.
Therefore, calculating BC.
Let it be y.
y² = 300²+150²-2*300*150cos120
y² = 157500
y = √(157500)
y = 150√(7) cm.
y = 396.8626966597 cm.
