Step-by-step explanation:
- Here, given that
- one of angle = sum of two other angle
- and ratio of other two angle = 4:5
- Let, the other two angle be 4x and 5x
- Now, one of angle = 4x +5x = 9x
- So, according to the question
- 9x + 4x + 5x = 180
- 18 x = 180
- x = 180/18 = 10°
- Hence, one of angle = 9x = 90°
- And other two angle = 4x and 5x = 40° and 50°
