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.

$125+10=135$
