Question

Whats the solve for x?

Answer 1

34°

Explanation:

Angles on a straight line add up to 180°.

Therefore, we equate the sum of all angles along the straight line to 180° to solve x:

`x\textdegree+(x+12)\textdegree+100\textdegree=180\textdegree\\\\2x\textdegree=(180-100-12)\textdegree\\\\2x=68\textdegree\\\\x=34\textdegree`

Hence x is 34°
