Which is a pair of vertical angles? ∠VRU and ∠SRT
∠TRS and ∠VRW
∠TRV and ∠WRU
∠WRV and ∠SRW

∠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.

The required equation is:

Step-by-step explanation:

The slope-intercept form of a line is given by:

For writing equation of a line, slope and a point is needed from which the line passes.

In order to find the slope of line perpendicular to PQ, we have to find slope of PQ first.

Slope is denoted by m and given by the formula

Given points are:

P(-1, -4) and Q (7, 1)

Putting the values

The product of slope of two pependicular lines is -1

Let m1 be the slope of line perpendicular to PQ

Now for the point, we have to find the point that divides PQ in ratio 3:2

The formula is:

Here

m = 3

n= 2

Putting the values

So we have to write equation of a line with slope -8/5 and passing through point (19/5, -1)

Putting the values in slope-intercept form

Putting the point in the equation

Putting the value of b

Hence,

The required equation is:
