Question

of the slopes of lines AB and XY are equal, then what can you say about lines AB and XY ​

Answer 1

Answer:

In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other. Here is a quick review of the slope/intercept form of a

Answer 2

Answer:

Step-by-step explanation:

Given lines AB and XY intersect at point O and  ∠AOX=3∠XOB

AB and XY inter sect at point O then opposite angle are equal each others

Then∠XOB=∠AOY

And ∠AOX=∠BOY=3∠XOB

We know that sum of all angle at a point total is 360

Then ∠AOX+∠BOX+∠BOY+∠AOY=360  

0

 

⇒3∠XOB+∠XOB+3∠XOB+∠XOB=360  

0

 

⇒8∠XOB=360  

0

⇒∠XOB=45  

0

 

∠XOB=∠AOY=45  

0

 

∠AOX=∠BOY=3∠XOB=3×45=135
