Answer:
36
Step-by-step explanation:
As the triangle ABC is isosceles so A and B has the same measures
And, the sum of the angles is 180°.
Therefore 2 times the measure of angle
B plus 120° = 180°,
So, the equation:
2x + 120 = 180
So x = 30
Now we have to apply the law of sin on the triangle BMC as shown below:
![\frac{12}{\sin30} = \frac{BC}{\sin 60}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B%5Csin30%7D%20%3D%20%5Cfrac%7BBC%7D%7B%5Csin%2060%7D)
Now calculate for BC
BC = 20.7
We use the law of sin again i.e
![\frac{AB}{\sin 120} = \frac{20.7}{\sin 30}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7B%5Csin%20120%7D%20%3D%20%5Cfrac%7B20.7%7D%7B%5Csin%2030%7D)
So AB is 36
That's equivalent to 216^(1/3) over 3^2, or
6
