1. Answer:

   45°, 60° and 75°

   Step-by-step explanation:

   Let the ratio 3:4:5 be 3x 4x and 5x.

   According to question:-

   3x + 4x + 5x = 180°(angle sum property)

   12x = 180°

   x = 180°/12

   x = 15°

   3x = 3*15° = 45°

   4x = 4*15° = 60°

   5x = 5*15° = 75°

2. Answer:

   let three angles of a triangle are 3x,4x and 5x

   sum of all angle of a triangle is 180°

   A.T.Q

   3x°+4x°+5x°=180°

   12x°=180°

   x°=180°/12

   x°=15°
