Answer: 14Step-by-step explanation:Since it is a right angles triangle , Pythagoras theorem will come into play,which states that;the square of the hypotenuses = square of the adjacent + square of the opposite , that is[tex]22^{2}[/tex] = [tex](RT)^{2}[/tex] + [tex]17^{2}[/tex]Therefore:[tex](RT)^{2}[/tex] = [tex]22^{2}[/tex] - [tex]17^{2}[/tex][tex](RT)^{2}[/tex] = 484 - 289[tex](RT)^{2}[/tex] = 195RT = [tex]\sqrt{195}[/tex]RT = 13.96RT≈ 14
