Which two theorems would justify that m∠4 = m∠6, given that m∠5 = m∠6 in the diagram below?
My name is Ann [436]

Answer: D) vertical angles theorem, alternate interior angles theorem

Angle 5 = Angle 6 by the alternate interior angles theorem

Angle 5 = angle 4 by the vertical angles theorem

By the transitive property, we can then say angle 4 = angle 6. These angles are also corresponding angles.

We won't use the angle addition theorem or the right angles theorem.

4 teammates share 5 granola bars equally. How much of a bar dows each person get?
worty [1.4K]
So it would be 5 divided by four. You cannot do that, so the closest number you could get to is 4. Which means each teammate gets 1 granola bar. The sentence for that would be: 5 divided by 4 = 1 remainder 1.
