I'm confused on how to find x​

Mathematics
1 answer:
azamat2 years ago
7 0

Answer:

x = 2

Step-by-step explanation:

Since this is a 45-45-90 triangle, the 2 legs will be the same, meaning that y will also be \sqrt2.

We can then solve for x using the Pythagorean theorem:

\sqrt2^2+\sqrt2^2=x^2\\2+2=x^2\\4=x^2\\x=2

Or, we could use a quicker approach: if the triangle is a 45-45-90 triangle, the hypotenuse will be \sqrt2 times the length of 1 leg. It essentially does the same thing; it's just faster so you could save time on tests.
