Question

What is the value of x?

Answer 1

`\implies x = 69`

Explanation:

By using external angle property,

• x + x - 23 = x + 46
• 2x - 23 = x + 46
• 2x - x = 46 + 23
• x = 69 Ans.

Note : External angle property theorem we can used when the sum of two internal angle is equal to external angle.
