Question

If(4x+35) and (3x-15) form a straight line , then find the value of x . What special name is given to these type of angles.

Answer 1

Since , (4x+35) and (3x-15) form a straight line.

They are adjacent angles. So,their sum must be 180.

(4x+35)+(3x-15)=180

7x+20=180

7x=180-20

7x=160

x=160/7

So,x= 22.9

the special name is adjacent angles.
