Answer 1

1) angles formed on straight line are equal to 180

So

x+x+2x=180

4x=180

x= 180/4=65

angles x=65 x=65 2x=2*65 = 130

2) vertical angles are equal so

angle x = 75 degree

Now the sum of angle x and z will be 180 because they are linear pair

angle x + angle z = 180

75 + z = 180

z = 180-75=105

we know vertical angles are equal so

angle y =z= 105

3) angle ABC + angle CBD= 180

(angles formed on straight line are equal to 180)

inserting values we get

2y-30 + 70 = 180

2y +40 = 180

2y = 180-40=140

y=140/2=70

so value of angle ABC

2y-30

inserting value of y we get

2*70-30=140-30=110

In this question u can just substract 70 from 180 instead of showing these steps

HOPE THIS WAS HELPFUL FOR U
