Answer 2

Explicație pas cu pas:

$\dfrac{\measuredangle AOB}{5} = \dfrac{\measuredangle BOC}{6} = \dfrac{\measuredangle COD}{2} = \dfrac{\measuredangle DOE}{4} = \dfrac{\measuredangle EOA}{7} =$

$= \dfrac{\measuredangle AOB + \measuredangle BOC + \measuredangle COD + \measuredangle DOE + \measuredangle EOA}{5+6+2+4+7}= \dfrac{360 \degree}{24} = 15 \degree$

=>

$\dfrac{\measuredangle AOB}{5} = 15 \degree \implies \measuredangle AOB = \ 75 \degree \\ \dfrac{\measuredangle BOC}{6} = 15 \degree \implies \measuredangle BOC = \ 90 \degree \\ \dfrac{\measuredangle COD}{2} = 15 \degree \implies \measuredangle COD = \ 30 \degree \\ \dfrac{\measuredangle DOE}{4} = 15 \degree \implies \measuredangle DOE = \ 60 \degree \\ \dfrac{\measuredangle EOA}{7} = 15 \degree \implies \measuredangle EOA = 105 \degree$
