Question

in fig.9.45 if ab perpendicular BC then X=​

Answer 1

Answer:

22°

Step-by-step explanation:

COB=32°(vertically opposite angle)

therefore DOB=x+32°

(x+14°)+(x+32°)+90°=180°

2x=180-90-46=44°

x=22°

Answer 2

Answer:

Sum of angles of triangle is 180°

So, DCO+AOC+CDO=180°

122°+x°+x+14°=180°

122+2x°+14°=180°

136+2x=180°

2x=44°

x=22°

Option B is correct
