anlgle a is twice angle b . if their sum is 132 degree, find each angle

Sagot :

Riza1viz
[tex]\measuredangle : \ a=2\cdot \measuredangle \ b \\\measuredangle : \ b \\\\\measuredangle \ a +\ \measuredangle \ b = 132^o \\2b+b=132 \\3b=132 \ \ | \ divide \ both \ sides\ by\ 3 \\\\\measuredangle \ b=44^o \\\measuredangle \ a=2\cdot 44^o=88^o[/tex]
44

2x+x=132
3x=132
\frac{3x}{3} = \frac{132}{3} (divide both by 3)
x=44

To Check:
2x+x=132
2(44)+44=132
88+44=132
