What is an angle?

"It is formed when two straight lines meet at a common endpoint."

What is triangle?

"It is a three-sided polygon that consists of three edges and three vertices."

For given example,

We have been given the angles x, 2x, 39

(Assuming these angles are the three angles of a triangle)

We know, the sum of all angles of the triangle is 180°.

⇒ x + 2x + 39 = 180°

⇒ 3x + 39 = 180°

⇒ 3x = 141

⇒ x = 141/3

⇒ x = 47

Therefore, the value of x is 47.

The correct answer is option (B).
