Answer 1

Step-by-step explanation:

Let their sides are 3x , 4x, 5x

A/Q,

perimeter of triangle = 3x + 4x + 5x = 48

=> 12x = 48

=> x = 4

Then sides are 12cm , 16cm , 20 cm

Answer 2

Answer:

45, 60,75

Step-by-step explanation:

Let angles be:3x,4x,5x,

Sum of all angle of triangle=180

3x+4x+5x=180

12x=180

x=180/12

x=15

So angle are 45,60 and 75.
