Answer 1

Answer:

12

Step-by-step explanation:

4x+5x+6x = 180

15x = 180

x = 180/15

x = 12

4x =4×15 = 60

5x = 5×15 = 75

6x= 6× 15 = 90

Answer 2

Answer:

let the common ratio be x

then,

4:5:6=4x:5x:6x

4x+5x+6x=180°. (angle sum property)

15x=180°

x=180/15

x=12

so

4x=4×12=48°

5x=5×12=60°

6x=6×12=72°

hence 4:5:6 = 48°:60°:72
