Question

The angles of a quadrilateral are in the ratio 3:4:5:6. The largest angle is
a) 80
b) 150°
c) 120°
d) 100°​

Answer 1

Answer:

Hey mate! Here's your answer

Step-by-step explanation:

Let the angkes be 3x,4x,5x,6x

Since the sum of all angles of quadrilateral is 360°

therefore 3x+4x+5x+6x= 360°

18x=360°

x=360°/ 18

x= 20°

largest angle is 6x

therefore, 6x= 6×20°

120°
