Question

PLEASE HELP points​ P, Q,​ R, and S are collinear. Point Q is between P and​ R, R is between Q and​ S, and pg=rs. If PS=25 and PR​,=18 what is the value of​ QR? PLEASE HELP

Answer 1

QR = 11

Explanation:

The points all lie on the same line , then

PQ + QR + RS = PS , that is

PR + RS = PS , substitute values

18 + RS = 25 ( subtract 18 from both sides )

RS = 7

Given PQ = RS = 7 , then

PQ + QR = 18 , that is

7 + QR = 18 ( subtract 7 from both sides )

QR = 11
