Answer:

Step-by-step explanation:

since it is an isosceles triangle other two angles are 45 and 45 degree.

take 45 degree as reference angle

using sin rule

sin 45=opposite/hypotenuse

1/[tex]\sqrt{2[/tex]=x/[tex]\sqrt{12[/tex]

do cross multiplication

x[tex]\sqrt{2[/tex]=[tex]\sqrt{12[/tex]

x=[tex]\sqrt{12[/tex]/[tex]\sqrt{2[/tex]

x=[tex]\sqrt{3[/tex]
