Answer 1

Hello,

Answer:

`\bullet\:\:\:(2x+40)^(\circ) = 110^(\circ)`

`\iff 2x+40=110`

`\iff 2x=110-40`

`\iff 2x=70`

`\iff x= (70)/(2)`

`\iff \boxed{x=35}`

`\\`

`\bullet\:\:\:2* 110 ^(\circ) +2* (y+20)^(\circ) = 360^(\circ)`

`\iff220^(\circ) +2(y+20)^(\circ)=360^(\circ)`

`\iff2(y+20)^(\circ)=360^(\circ)-220^(\circ)`

`\iff2(y+20)^(\circ)=140^(\circ)`

`\iff(y+20)^(\circ)=(140^(\circ))/(2)`

`\iff(y+20)^(\circ)=70^(\circ)`

`\iff y+20=70`

`\iff y=70-20`

`\iff \boxed{y=50}`
