Answer 1

b= \frac{l}{cos (30)} = \frac{8*2}{ \sqrt{3} } =9.24 \\ tg(30)= \frac{h}{l} =>h=l*tg(30)=8* \frac{ \sqrt{3} }{3} =4.62" alt="cos( 30)= \frac{l}{b}=>b= \frac{l}{cos (30)} = \frac{8*2}{ \sqrt{3} } =9.24 \\ tg(30)= \frac{h}{l} =>h=l*tg(30)=8* \frac{ \sqrt{3} }{3} =4.62" align="absmiddle" class="latex-formula">
