Answer:
x = 1 degree
Step-by-step explanation:
Using the Pythagorean theorem, 
we can find the unknown side then use SOHCAHTOA to find the unknown angle
First step:
Take the square root of both sides
Now to find the angle use SOHCAHTOA
Cosine = 
(The side we found is adjacent)(Hypotenuse is the longest side)
= 
= 0.999
Approximately 1 degree.
