Answer 1

Given : In a triangle One angle  is 15 deg more than 2nd angle &  third angle is 25 deg more than  2nd angle

To find : Angles of triangles

Solution:

Let say second angle  = A

1st angle = A  + 15°

3rd Angle = A + 25°

Sum of all angles of a triangle = 180°

=> A + A + 15° + A + 25° = 180

=> 3A + 40°  = 180°

=> 3A = 140°

=> A  = 140/3  

140/3 + 15  =  185/3

140/3 + 25  = 215/3

Angles are  140/3  ,  185/3 ,  215/3   Degrees
