Question

find x in the following​

Answer 1

Answer:-

x = 20°

Step-by-step explanation:-

∵ ∠ABO = 3x + 10°

∴ ∠AOB = 3x + 10° (∠s opposite to equal sides are equal)

⇒ ∠COD = 3x + 10° (VERTICALLY OPPOSITE)

Now, in ΔCOD,

∠COD + ∠DCO + ∠CDO = 180° ( ANGLE SUM PROPERTY OF A TRIANGLE )

→ 3x + 10 + 2x + 3x + 10 [∠COD = ∠CDO(∵∠s opposite to equal sides are equal)] = 180°

⇒ 8x + 20 = 180°

→ 8x = 160 °

⇒ x = 20°
