Which is a pair of vertical angles?
malfutka [58]

Answer: ∠TRS and ∠VRW  (Choice B)

========================================================

Explanation:

Ignore ray RU. I would redraw the entire thing without ray RU as part of the picture. See below.

Notice how lines TW and SV intersect to form an X shape.

The angles TRS and VRW shown in red are opposite one another, so we consider them to be vertical angles. Vertical angles are always congruent.

If y varies directly with x, Write an equation relating x and y when y = -30 and x = 6.
ziro4ka [17]

Answer:

y=-5x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

so

For x=6,y=-30

substitute

y/x=k------> k=-30/6=-5

therefore

y=-5x
