Question

Aflati masurile unghiurilor unui triunghi cu lugimile laturile 3 cm 3(radical)3 si 6 cm.Suneti-mi va rog ce formula ati folosit

Answer 1

[tex]\sf Faci~Pitagora~ca~sa~vezi~daca~triunghiul~este~dreptunghic: \\ \\ 3^2+(3 \sqrt{3})^2=6^2 \\ \\ 9+27=36 (adevarat) \longrightarrow \triangle~este~dreptunghic. \\ \\ Faci~sinusul~unghiului~opus~laturii~de~3 \sqrt{3}: \\ \\ sin= \frac{\not 3 \sqrt{3}}{^2\not 6}= \frac{ \sqrt{3}}{2} \longrightarrow \boxed{\sf \measuredangle 1=60^o} \\ \\ \boxed{\sf \measuredangle2=90^o} \\ \\ \measuredangle3=180-90-60 \\ \\ \boxed{\sf \measureangle3=30^o}[/tex]
