X+X=180(linear pair) 2x=180 X=90

Sia ? 5 years, 2 months ago

{tex}\angle AOC{/tex} + {tex}\angle BOC{/tex} = {tex}\angle AOB{/tex}
{tex}\angle AOC{/tex} + {tex}\angle COB{/tex} = 180^o (liner pair)
6x + 30^o + 4x = 180^o
10x + 30^o = 180^o
10x = 180^o - 30^o
10x = 150^o
x = {tex}\frac {150}{10}{/tex} = 15
x = 15^o
