b)Determina masura a doua unghiuri complementare, stiind ca masura unuia dintre ele reprezinta doua treimi din masura celuilalt.

Answer 1

A) <AOB + <COB = 180 grade
<AOB * 2/3 = <COB

<AOB + <AOB*2/3 = 180 gr
<AOB*5/3=180 gr
<AOB = 108 gr
<COB = 72 gr

B) <AOB + <COB = 90 grade
<AOB + <AOB*2/3 = 90 gr
<AOB*5/3 = 90 gr
<AOB = 54 gr
<COB=36 gr
