​

Answer 1

Answer:

Letanglesoftrianglebex,3xand5x

Asweknowthat

⇒Sumofallanglesoftriangle=180

∘

⇒∴x+3x+5x=180

∘

⇒9x=180

∘

x=20

∘

,3x=60

∘

and5x=100

∘

Ans.

Answer 2

Answer:

X + 3x + 5x = 180

9x = 180

x = 180 / 9

20 = x

1 angle = 20

2 angle = 20 × 3 = 60

3 angle = 20 × 5 = 100
