Answer 2

Answer:

Step-by-step explanation:

let the third angle be x

therefore the other angles are 75% and 35% of x

first angle = 75x/100 = 3x/4

second angle = 35x/100 = 7x/20

third angle is x

now as we know the sum of all angles of a triangle is 180

x + 3x/4 + 7x/20 = 180

taking LCM 20, we get

(20x+15x+7x) / 20 = 180

42x/20=180

x = 85.7 (approx)
