Answer 1

NO.S BE 3X…4X AND 5X
3X+5X=4X+64
4X=64
X=16

Answer 2

Answer:

39,52 and 65

Explanation:

There should be new triangle for propionate to 3:4:5
Let take x and multiple it to 3:4:5 to make new triangle 
3x+5x=4x+52
3x+5x−4x=52
or
4x=52
or
x=524
or
x=13

Put the value of x =13 in 3x+5x=4x+52
3⋅13+5⋅13=4⋅13+52
or
39+65=52+52

or
104=104

Hence the numbers are 39,52 and 65
