Answer 1

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/$\sqrt{2$=x/$\sqrt{12$

do cross multiplication

x$\sqrt{2$=$\sqrt{12$

x=$\sqrt{12$/$\sqrt{2$

x=$\sqrt{3$
