Given: angle BOD = 126°
To find : x and y
Solution: since BA is a line.
so,angle BOD + angle DOA =180° (linear pair)
126°+2y=180°
2y = 180°-126°
2y= 54°
y=54°/2
y=27°
since CD is a line.
so, angleBOD+angleCOB =180° (linear pair)
126°+3x=180°
3x=180°-126°
3x=54°
x=54°/3
x=18°
Hence y=27°
x=18°
hope you find it good ^_^
