Question

What is the closest length of RT?

Answer 1

c)14

Explanation:

Pythagorean theorem:

TR² + RG² = TG²

TR² + 17² = 22²

TR² = 22² - 17² =(22+17)(22-17)

= 39*5 = 195 ≈ 196

TR =√196 = 14

Answer 2

Answer: 14

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 =
`√(195)`

RT = 13.96

RT≈ 14
