Question

Can somebody please help me!!

Answer 1

120+100+120+x+10+120+x=720
2x+470=720
subtract 720- 470
2x=250
x=250/2
x=125
125+10=135
hope it helps

Answer 2

So to solve for x, you'll need to combine all the angles and equal it to 720, and from there we can solve.


`120+100+120+x+10+120+x=720`

Combine like terms to get
`2x+470=720`

Subtract 470 on each side to get
`2x=250`

Then just divide on each side and you'll get
`x=125`


To find the value of the (x+10) angle, just substitute 125 for x and solve.


`125+10=135`
