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)

Answer 1

The equation that can be used to solve for x is:

∠1 + ∠2 = 100°

Substituting the given values:

20° + (3x + 15)° = 100°

Answer 2

3x+115=20

3x−20=100

3x−100=20

3x+35=100
are the answers, choose

Answer 3

The correct answer is:

3x + 15 = 100
