Explicație pas cu pas:

tg B = AC/AB

AB = AC/tgB = 6/(2/3) = 6*3/2 = 9 cm

[tex]\bf tgB = \dfrac{AC}{AB}[/tex]

[tex]\bf AB = \dfrac{AC}{tgB}}[/tex]

[tex]\bf AB = \dfrac{6}{\dfrac{2}{3}}[/tex]

[tex]\bf AB = \dfrac{6}{1}:{\dfrac{2}{3}}[/tex]

[tex]\bf AB = \dfrac{6}{1}\cdot{\dfrac{3}{2}}[/tex]

[tex]\bf AB = \dfrac{\not6}{1}\cdot{\dfrac{3}{\not2}}[/tex]

[tex]\bf AB = \dfrac{3}{1}\cdot{\dfrac{3}{1}}[/tex]

[tex]\boxed{\bf AB = 9\:cm}[/tex]
