Answer:
x = 37
Step-by-step explanation:
by using vertically opp angles
2x + 1 = 75
[tex]x = \frac{75 - 1}{2} = 37[/tex]
x=37
When 2 lines cross like this, the angles on either side must add up to 180°, or a flat line. This means the angles across from each other, in this case 75° and (2x+1) ° are equal. So, we set 75=2x+1 and solve.
75-1=2x
74=2x
74/2=2x/2
