Question

the angles of a quadrilateral are in the ratio of 3:4:5:6. find the measure of the angle​

Answer 1

Answer:

Let the first angle be 3x

Second angle be 4x

Third angle be 5x

Forth angle be 6x

ATQ

3x+4x+5x+6x =360°

18x = 360°

x= 360÷18

x= 20

1st angle = 3x = 3×20 = 60°

2nd angle = 4x = 4×20 = 80°

3d angle = 5x = 5×20 = 100°

4th angle = 6x = 6×20 = 120°

Answer 2

Answer:

60°, 80°,100°and 120°

Explanation:

A.T.Q

first angle= 3x

second angle=4x

third angle = 5x

fourth angle= 6x

so,

3x+4x+5x+6x=360

(sum of angles of a quadrilateral is 360°)

18x=360

x= 20

hence,

first angle= 3(20)=60°

second angle=4(20)=80°

third angle=5(20)=100°

fourth angle=6(20)= 120°
