Z is centroid of triangle RST. What is RW, if RV=4x+3, WS=5x-1, and VT=2x+9?
1 answer:
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
