In a diagram, ∠3 and ∠5 are vertical angles, and ∠4 is a supplementary angle with ∠5. If m∠3=67°, what equation can you write to solve for m∠4?(1 point)%0D%0Am∠4+°=°

Answer 1

We know that vertical angles are congruent, which means that m∠3 = m∠5. We also know that supplementary angles add up to 180°, which means that m∠4 + m∠5 = 180°.

Since m∠3 = 67° and m∠3 = m∠5, we can substitute 67° for m∠3 and m∠5 in the equation m∠4 + m∠5 = 180°.

So the equation to solve for m∠4 is:

m∠4 + 67° = 180°.
