Answer:

  • x = 25°

Explanation:

From the given figure It is isosceles triangle. Here 2x+ 10 and 60° are the opposite angles.

The two angles of an isosceles triangle, opposite to equal sides, are equal in measure.


\sf 2x + 10 = 60


\sf 2x = 60 - 10


\sf 2x = 50

Divide both sides by 2 ,


\sf x = 25°
