19) on your own :)
i hope this helped!! :D
Can't tell without a diagram.
But, it looks like you are dealing with the standard parallel lines
and a transversal cutting both
In that case,
1. alternate angles are equal
2. corresponding angles are equal
3. interior angles on the same side of the transversal are supplementary
connexus students only is wrong 7/18
someone pls give all the answers pls i am so behind i need help
No connexus student is right on 18 idk about 7 my question is different. She did very well on her answers.
To identify a pair of vertical angles, you need to look for intersecting lines or line segments. Vertical angles are formed when two lines intersect, and they share a common vertex but have different rays.
In the given options:
- ∠2 and ∠5 are vertical angles because they are opposite angles formed by the intersection of lines.
- ∠2 and ∠6 are not vertical angles because they are adjacent angles and not opposite angles.
- ∠3 and ∠4 are not vertical angles because they are also adjacent angles.
- ∠5 and ∠6 are not vertical angles as they are also adjacent angles.
Therefore, the correct answer is:
1. ∠2 and ∠5
For the second question, you're given that m ∠ is equal to 37. We need to find m∠4. It's important to understand that vertical angles are always congruent (they have equal measures). Since ∠2 and ∠5 are vertical angles, and m ∠ is 37, it means that m∠2 = 37.
Since ∠2 and ∠4 are adjacent angles formed by the same rays, they form a linear pair. In a linear pair, adjacent angles are supplementary, which means their measures add up to 180 degrees.
Therefore, to find m∠4, we subtract the measure of ∠2 from 180:
m∠4 = 180 - m∠2 = 180 - 37 = 143.
Therefore, the correct answer is:
2. m∠4 = 143
