Answer 1

Answer:

Let the ratio be x

So, Sides of the triangle are 3x, 4x and 5x

We know that,

Sum of all the interior angles and the triangle is 180 degree

According to the question

3x +4x +5x = 180

12x = 180

x = 15

Hence,

all the angles of the triangle are 45, 60 and 75 degrees

Answer 2

Answer:

3x+4x+5x =180

12x=180

x=180/12

= 15

1st angle= 3*15= 45°

2nd angle= 4*15=60

3rd angle= 5*15=75
