good morning friends
hey your answer is here:-
sum of the angles in a triangle is 180°
two angles is 4:5
= 4x + 5x = 180°
= 9x = 180°
X = 180 /9
X = 20
4x = 4× 20 = 80
5x = 5 × 20 = 100
the third is is equal to the sum of the two angles
hope it helps

let the angle be x and third side is 4x+5x =9x. 4x + 5x + 9x =180 (sum of angle is 180). 18x =180 => x =180÷18 = 10. 1st angle is 4× 10 =40. 2nd angle is 5×10=50. and 3rd angle is 9×10 =90
