Answer:

x= 40

Explanation:

sum of angle on a straight line= 180;

To find X,

sum of angles = 180

x+(4x-20)= 180

: x= 180- [x+(4x-20)]

opening the brackets,

= 180-x-4x+20= 0

taking like terms:

= -x-4x+180+20= 0

= -5x+200=0

= -5x= -200

= x= 200/5

x= 40°

Answer:

x=40

Explanation:

I went through each answer one by one and the only one that satisfies the question is 40.

The line equals 180°, so x + (4x-20) must equal 180.

x+(4x-20)

40+(4(40)-20)

40+(160-20)

40+140=180

x=40
