Question

Question 25. In the given figure,find the value of y​

Answer 1

Answer:

y=20°

Step-by-step explanation:

<1=90° ( vertically opposite angles are always equal)

<COB and <BOD form a linear pair. So sum of <COE and <EOB = <COB

30°+90°=120°

now to find the value of <BOD,

120°+3y=180° ( linear pair )

3y=180°-120°

3y=60°

y=60°/3

y=20°
