Answer:
x=31
Explanation:
Since these angles are on a straight line, they are supplementary (combine to make 180 degrees. Therefore we can set up an equation to find x.
(5x-16)+(x+10)=180
Drop the parentheses.
5x-16+x+10=180
Combine like terms.
6x-6=180
Add 6 to both sides.
6x=186
Divide both sides by 6.
x=31
HTH :)
