Question

What is the closest length of RT?

Answer 1

Answer: 14

Step-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

$22^{2}$ = $(RT)^{2}$ + $17^{2}$

Therefore:

$(RT)^{2}$ = $22^{2}$ - $17^{2}$

$(RT)^{2}$ = 484 - 289

$(RT)^{2}$ = 195

RT = $\sqrt{195}$

RT = 13.96

RT≈ 14

Answer 2

Answer:

c)14

Step-by-step explanation:

Pythagorean theorem:

TR² + RG² = TG²

TR² + 17² = 22²

TR² = 22² - 17² =(22+17)(22-17)            

  = 39*5 = 195 ≈ 196

TR =√196 = 14
