Answer 1

x = 9

Explanation:

Of course I'll do very simple explanation!

every time you see a straight line (nondiagonal) it measures 180°.

so if we're trying to solve for x in this case, we'll subtract 180° - 40° = 140°.

Then use the statement to solve for x

`10x+50=140`

`10x-50` = - 50 Subtract 50 from both sides

`10x`
`=` 90 Divide 10 from both sides

x = 9
