Geometry math question no Guessing and Please show work

Answer 1

This is one of the two tired triangles of trig you should memorize. An isosceles right triangle has its sides in ratio
`1:1:\sqrt 2`. That means the hypotenuse is the square root of two times either side.

`u = √(2) * √(2) = 2`

Answer: C

If you didn't know you could write

`v = \sqrt 2`

`v^2 + v^2 = u^2`

`u^2 = 2 + 2 = 4`

`u = 2`
