Question

Please help me with #16 I am really bad at doing fractions

Answer 1

To see if it's a right triangle we need to determine if a²+b²=c²
(
`(3)/(20)`)² + (
`(1)/(5)`)² =
`(1)/(4)`

`(9)/(400)` +
`(1)/(25)` =
`(1)/(16)`

`(9)/(400)` +
`(16)/(400)` =
`(25)/(400)`

`(25)/(400)` =
`(25)/(400)`

So it is a right triangle
