Two adjacent angles have a sum of 100°. The angles have measures ∠1 = 20° and ∠2 = (3x + 15)°. What equation can be used to solve for x?(1 point)

3x+115=20
3 x plus 115 is equal to 20
3x−20=100
3 x minus 20 is equal to 100
3x−100=20
3 x minus 100 is equal to 20
3x+35=100
The correct equation that can be used to solve for x is 3x + 15 + 20 = 100.
THATS WRONG
I apologize for the mistake. Let me correct it.
The correct equation that can be used to solve for x is 20 + (3x + 15) = 100.
This equation represents the sum of the two adjacent angles being equal to 100 degrees.
