Answer 2

Given,
The ratio of the sides of the triangle = 3:4:5
Let the first side be 3x
Let the second side be 4x
Let the third side be 5x


Solution,
Sum of all sides of the triangle = 180
3x + 4x + 5x = 180
12x = 180
x = 180/12
x = 15

So if x = 15
Then,
First side = 3x
= 3 x 15 = 45
Second side = 4x
= 4 x 15 = 60
Third side = 5x
= 5 x 15 = 75

The answers are 45 degree , 60 degree and 75 degree
