Question

If the measures of a angle in a quadrilateral are 3x, 3x, 5x and 7x , then the value of x is 
​

Answer 1

Answer:

x = 20°

Step-by-step explanation:

3x +3x +5x +7x = 360° (Since all angles in a quadrilateral make 360°)

18x = 360

x = 360/18

x = 20

Answer 2

Answer:

#sum of all the angles of a quadrilateral is =360

#let the angles be = 3x,3x,5x,7x

#3x+3x+5x+7x=360

#18x=360

#x=360/18

#x=20

#so value of x=20 ,thus angles are :

#3(20)=60°

#3(20)=60°

#5(20)=100°

#7(20)=140°

(to check : add all the angles and there sum will be 360°so it proves that it is a quadrilateral )
