Question

What is the value for y?
5 square root 2
5 square root 3
10
5

Answer 1

and the value for x.

Answer 2

5=y*cos45° => y = 5/cos45 => \[5\frac{2}{\sqrt2}\] => answer is A.

Answer 3

x = y*sen45 => x = \[5\sqrt2 * \frac{\sqrt2}{2}\] = 5

Answer 4

x=5
\[5^2+5^2=y^2 =>50=y^2 =>y=\sqrt{50}= \sqrt{25} \sqrt{2}=5 \sqrt{2}\]

Answer 5

this is a 45 45 90 triangle
so x would have to = 5
