Answer:
∠TRV and ∠WRS or ∠TRS and ∠WRV
Step-by-step explanation:
Vertical angles are angles that share a vertex and have sides that are opposite rays. That is, the opposites of the rays that form one of the angles are the rays that form the other angle.
__
Where lines cross, two pairs of vertical angles are formed. In your diagram, those pairs are ...
∠TRV and ∠WRS . . . . one vertical angle pair
∠TRS and ∠WRV . . . . another vertical angle pair
_____
<em>Additional comment</em>
In this diagram, the ray RU is of no consequence with respect to any vertical angles. It can be ignored.
The vertical angles will each have one red ray and one blue ray as sides. These rays have end point R. No sides are shared.
Answer:
The answer is,
Step-by-step explanation:
Firstly, you have to get rid of fraction by multiplying (r-3) to both side and expand out:
t × (r-3) = r/(r-3) × (r-3)
rt - 3t = r
Then you have to move all the "r" variables to one side and other variables to the other side:
rt - r = 3t
You can make "r" as a subject by taking out the common term, you can see that the common term on the left is "r" so you can bring out:
r(t-1) = 3t
r = 3t/(t-1)
