Question

it is given figure a b parallel CD if Angle Bao is equals to 110 degree and Angle is equal to 20 degree and Angle or CD = 2 X degree then find the value of x

Answer 1

angle x=110 degree if tu need steps told me

Answer 2

Answer:

x = 130°

Step-by-step explanation:

CONSTRUCTION : Extend CD parallel to AB up to point E at AO

Now, AB ║ DE

∠BAO = ∠DEO ( Corresponding angles are equal)

Now, ∠BAO = 110°

⇒ ∠DEO = 110°

Now, using exterior angle property, exterior angle is equal to sum of measure of two opposite angles.

So, x is the exterior angle of ΔCEO

⇒ x = ∠CEO + ∠COA

⇒ x = 110 + 20

⇒ x = 130°
