Question

plz give me solution of 4th 5th and 6th problem

Answer 1

4) y= 60 degrees and x = 40 degrees

5)y= 90 degrees and x= 45 degrees

6) y= 130 degrees and x = 50 degrees

Answer 2

60=angle Y by vertically opposite angle
35 is equal to the angle which is between x and 60 again by vertically opposite angle then Y+45+x+35 by angrezon straight line

5 ques. 90 is equal to angle Y by vertically opposite angle now u know the value of Y then add angle Y and x and 2x-30 by angles on straight line

6ques. 130 is equal to angle Y by vertically opposite angle and to find the value of x u need to do 130 + x=180by linear pair u will find the value of x
