let the common ratio = x
3x:4x:5x
sum of angles of a triangle = 180
3x+4x+5x = 180
12x = 180
x = 180/12
x = 15
3(15) = 45 degree
4(15) = 60 degree
5(15) = 75 degree

Here is your answer dear ⬇️⬇️


▶️ Let the first angle be 3x

▶️Let the second angle be 4x

▶️Let the third angle be 5x


⚜️ Measure of angles in a triangle = 180°


ATQ,

3x + 4x + 5x = 180

12x = 180

x = \frac{180}{12}

x = 15


✔️ First angle is 3x

i.e. 3 × x

= 3 × 15

= 45°


✔️ Second angle is 4x

i.e. 4 × x

= 4 × 15

60°



✔️ Third angle is 5x

i.e. 5 × x

= 5 × 15

= 75°
