Answer 1

Răspuns:

Explicație pas cu pas:

tg B = AC/AB

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

Answer 2

$\bf tgB = \dfrac{AC}{AB}$

$\bf AB = \dfrac{AC}{tgB}}$

$\bf AB = \dfrac{6}{\dfrac{2}{3}}$

$\bf AB = \dfrac{6}{1}:{\dfrac{2}{3}}$

$\bf AB = \dfrac{6}{1}\cdot{\dfrac{3}{2}}$

$\bf AB = \dfrac{\not6}{1}\cdot{\dfrac{3}{\not2}}$

$\bf AB = \dfrac{3}{1}\cdot{\dfrac{3}{1}}$

$\boxed{\bf AB = 9\:cm}$
