Question

Ajuda nesse triangulo PF!!

Answer 1

$5x+ \dfrac{x}{2} + \dfrac{x}{3} =180\º$

$6.5x+ 3.x + 2.x =6.(180\º)$

$30x+ 3x + 2x =1080\º$

$35x =1080\º$

$x= \dfrac{1080\º}{35}$

$x=30,857\º=30\º51'26''$

$5x=5.(30,857\º)=154,286\º=154\º17'9''$

$\dfrac{x}{2} = \dfrac{30,857\º}{2} =15,429\º=15\º25'43''$

$\dfrac{x}{3} = \dfrac{30,857\º}{3} =10,286\º=10\º17'9''$
