Answer:
The angles are 135°, 105° , 45° , 75°
Step-by-step explanation:
The angles of a triangle are in the ratio 9:7:3:5
Let the actual ratio be 9k:7k:3k:5k -------->(1)
The sum of angles of Quadrilateral is 360°
⇒ 9k:7k:3k:5k = 360°
⇒ 24k = 360
⇒ k = 360/24 = 15
substute 'k' in (1)
First angle (9 × 15)° = 135°
Second angle (7 × 15)° = 105°
Third angle (3 × 15)° = 45°
Fourth angle = (5 × 15)° = 75°
