Answer:


\large\boxed{RT=√(165)}

Explanation:

PT = NT. Therefore we have the equation:


4x-17=x+10 add 17 to both sides


4x=x+27 subtract 4x from both sides


3x=27 divide both sides by 3


x=9

Therefore


NT=4(9)-17=36-17=19

Use the Pythagorean theorem:


RT^2+RN^2=NT^2

Substitute RN = 14 and NT = 19:


RT^2+14^2=19^2


RT^2+196=361 subtract 196 from both sides


RT^2=165\to RT=√(165)
