Question

need some help with geo, could you explain how to do it as well so i know next time not needed but helpful

Answer 1

you can do this by finding the lengths of RT , RS and ST using the distance formula

RT = sqrt ((0- -5)^2 + (4 - -6)^2)
= sqrt (5^2 + 10^2) = sqrt 125

RS = sqrt ((-3- -5)^2 + (-2 - -6)^2))
= sqrt ( 2^2 + 4^2) = sqrt 20

ST = sqrt 125 - sqrt 20

RS / ST = sqrt 20 / (sqrt 125-sqrt 20)

so the ratio RS:ST = 2:3
