Question

Calculati aria si inaltimea corespunzatoare ipotenuzei unui triunghi dreptunghic cu catetele de 16 si 12 cm.

Answer 1

 [tex]A_{\Delta}=\frac{16\cdot12}{2}=96cm^2\;;\\ A_{\Delta}=\frac{b\cdot{h_b}}{2}=96cm^2 \;\;unde\;b=\sqrt{16^2+12^2}=20cm\;;\\ \Rghtarrow\;\;h_b=96 : (20:2)=9,6cm\;;\\ [/tex]
