Answer 2

Answer:

40°,50°,90° is ur answer...

Step-by-step explanation:

Sum of all angles of a triangle = 180°

Ratio between three angle = 4 : 5 : 9

Let the number be x

4 + 5 + 9 = 18

= 18x

180° = 18x

Thus, x = 180÷18

= 10°

The measure of 1st angle = 4 × 10 = 40°

The measure of 2nd angle = 5 × 10 = 50°

The measure of 3rd angle = 9 × 10 = 90°
