Answer 1

Answer:

I hope

Step-by-step explanation:

x+(x-20)+(x-40)=180

when x=80

80+(80-20)+(80-40)

=80+60+40=180

so, x=80

Answer 2

Answer:

Step-by-step explanation:

Add the values given equal to 180degrees, collect the like terms .x +x+x-20-40=180°.3x=180°+60°.Then divide both sides by 3 to get the value of x.
