What are your thoughts regarding this problem? Have you been able to start the problem? If so, how far have you gotten?

oregonduck · Answer

i am stuck on how to start really

oregonduck · Answer

my older brother said this is how to solve it and there is the answer is it right?


Y+70+60=180°
y+130=180
y=180-130
y=50°
x+y=90°
x+50=90
x=90-50
x=40°

The given information says that x and y are vertical angles. What do you think we can conclude about the relationship between x and y?

oregonduck · Answer

they run across each other like an x?

hero · Answer

Vertical angles are congruent. In other words, they have the same measure.

oregonduck · Answer

oh...

hero · Answer

How do we write the relationship between two angles having the same measure?
