Question

Please help needed please ​

Answer 1

1.5

Explanation:

it is 1 and it a half so... 1.5

Answer 2

`√(3)`

Explanation:

Using the pythagoras theorem,

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

Wherein a is the long side (2)

and b = 1

Hence,

`2^2 = 1^2+c^2\\c^2 = 2^2 - 1^2\\c^2 = 4-1\\c^2 = 3\\c = √(3)`

Hence,

c = x =
`√(3)`
