Aleksandr-060686 [28]

Answer:

The true statement is <u>Line h has points on planes R, P, and T</u>

Step-by-step explanation:

The rest of the question is the attached figure

According to the graph, we will check which option is true.

a. Line h intersects line f at two points, A and B   (<u>Wrong</u>)

<u>Because</u>: h intersects line f at B only.

b. Line h is the intersection of planes R and T      (<u>Wrong</u>)

<u>Because</u>: g is the intersection of planes R and T

c. Line h intersects plane P at point C                   (<u>Wrong</u>)

<u>Because</u>: h intersects plane P at point B

d. Line h has points on planes R, P, and T             (<u>True</u>)        

<u>Because </u>h has the point B on the plane P, h has the point A on the plane T

and the points of h on the plane R

Z is centroid of triangle RST. What is RW, if RV=4x+3, WS=5x-1, and VT=2x+9?
vaieri [72.5K]
Given that Z is the centroid of a triangle RST. This means that Z is the point of intersection of the three medians of the triangle.

So,W is the midpoint of RSV is the midpoint of RTWe are given that:RV = 4x + 3 and VT = 2x + 9

Since V is the midpoint, then:RV = VT4x + 3 = 2x + 94x - 2x = 9 - 32x = 6x = 3

Now put the value of x in WS = 5x-1WS = 5x-1WS = 5(3) - 1 WS = 15 - 1 = 14WS = 14

Since W is the midpoint of RS, therefore RW = WSand WS = 14Therefore:
RW = 14
