Tema geometrie clasa a 7 a

Answer 1

Explicație pas cu pas:

$\mathcal{A}_{\triangle ABC} = \dfrac{h_{AB} \cdot AB}{2} \iff 24 = \dfrac{h_{AB} \cdot 6}{2} \\ h_{AB} = \dfrac{2 \cdot 24}{6} \implies h_{AB} = 8 \ cm$

$\mathcal{A}_{\triangle ABC} = \dfrac{h_{AC} \cdot AC}{2} \iff 24 = \dfrac{h_{AC} \cdot 8}{2} \\ h_{AC} = \dfrac{2 \cdot 24}{8} \implies h_{AC} = 6 \ cm$
