Answer:
[tex]\large\boxed{RT=\sqrt{165}}[/tex]
Step-by-step explanation:
PT = NT. Therefore we have the equation:
[tex]4x-17=x+10[/tex] add 17 to both sides
[tex]4x=x+27[/tex] subtract 4x from both sides
[tex]3x=27[/tex] divide both sides by 3
[tex]x=9[/tex]
Therefore
[tex]NT=4(9)-17=36-17=19[/tex]
Use the Pythagorean theorem:
[tex]RT^2+RN^2=NT^2[/tex]
Substitute RN = 14 and NT = 19:
[tex]RT^2+14^2=19^2[/tex]
[tex]RT^2+196=361[/tex] subtract 196 from both sides
[tex]RT^2=165\to RT=\sqrt{165}[/tex]
