Please help me on this question​

Answer 1

6.1 cm

Explanation:

We have to find the hypotenuse of the orange triangle which will be the leg of the green triangle

`a^(2)` +
`b^(2)` =
`c^(2)`

`4.2^(2)` +
`4^(2)` =
`c^(2)`

17.64 + 16 =
`c^(2)`

33.64 =
`c^(2)`

`√(33.64)` =
`c^(2)`

5.8 = c

`a^(2)` +
`b^(2)` =
`c^(2)`

`2^(2)` +
`5.8^(2)` =
`c^(2)`

4 + 33.64 =
`c^(2)`

37.64 =
`c^(2)`

`√(37.64)` =
`\sqrt{c^(2) }`

6.13514466007 = c This is a rounded number. This is an irrational number. It never repeats or terminates.

Rounded to 1 decimal place

6.1
