Can somebody help w this, please?

all you have to do is just re- arrange the angles and then add them up:0

Step-by-step explanation:

lol

x = 2

Step-by-step explanation:

We'll start with this useful fact about triangles: equal angles in a triangle sweep out equal sides. If a 45 degree angle here sweeps out a length of x, the other one must do the same, so the legs of this right triangle must both be x.

Next, we can use the Pythagorean Theorem to tie all of the triangle's lenghts together:

x² + x² = (√8)²

Finally, we can solve for x:

2x² = 8

x² = 4

x = 2.

the answer is a i belaeve atleast thats what my calculator just gfave me
