The value of  .
.

 
 
 

We know that,

 ➪ 125° +  + 30° = 180°
 + 30° = 180°
 ➪  + 155° = 180°
 + 155° = 180°
 ➪  = 180° - 155°
 = 180° - 155°
 ➪  = 25°
 = 25°
Therefore, the value of  is 25°.
 is 25°.
Now, the three angles of the triangle are 125°, 25° and 30°.

✒ 125° + 25° + 30° = 180°
✒ 180° = 180°
✒ L. H. S. = R. H. S.
