Please help me, and explain throughly how to do it because i want to try and do the rest myself :)

Side v is √2. Side u is 2

Step-by-step explanation: When you have a right triangle with one angle given as 45° the other angle is also 45° and the two sides are equal.

We can use the Pythagorean Theorem to calculate the length of the hypotenuse (opposite the 90° angle).

c² = a² + b²

Sides "√2" and v are a and b. c is the hypotenuse.

The Square of √2 is 2.

c² = 2+2. So c² = 4

The the Square root of both sides.

c = 2

It is also possible to calculate the lengths or angles using trigonometry sine, cosine, and tangent. You need a calculator for those functions.
