Accepted Solution

A:
Answer: 1) △XBR∼ΔYNJ .2) The scale factor of  ABCD to RSTU would be 1/2.Step-by-step explanation: We are given two triangles ΔXBR and ΔYNJ.Because all sides of ΔXBR and ΔYNJ are in same proportion.Therefore, ΔXBR and ΔYNJ are similar triangles.△XBR∼ΔYNJ ____________________________________________________In other figure we are given two rectangles ABCD and RSTU .Also given Rectangle ABCD is similar to rectangle RSTU .Let us check the proportion of the sides of the given rectangles.AD/UR = CD/UT50/25 = 90/252/1 = 2/1.Sides are in ratio 2:1.The scale factor of  ABCD to RSTU would be 1/2.Because all side of RSTU are 1/2 of sides of ABCD.
