Question

the angles of a quadrilateral are 4x,5x+10,7x-20 and 6+18 find the angle
​

Answer 1

Step-by-step explanation:

sum of angles in a quadrilateral is 360

therefore,

4x + 5x+ 10+ 7x -20 + 6x+18 = 360

22x + 8 = 360

22x = 360-8

22x = 352

X=352/22

X= 16

therefore the angles are

4×16= 64

5(16)+10 = 90

7(16)-20 = 92

6(16)+18 = 114
