Question

11. From the adjoining figure, find
(i) x
(ii) angle DAB
(iii) angle ADB​

Answer 1

Answer:

1) 24

2) 76

3) 82

Step-by-step explanation:

1) in the above quadrilateral the sum of angles=

3x+4+50+x+5x+8+3x+10=360

12x+72=360

12x=360-72

12x=288

x=288/12=24

so x=24

2) angle DAB= 3x+4=3*24+4=76

3)ADB =3x+10=3*24+10=72+10=82
