SOLUTION: Find the acute angle that satisfies the given equation. Give 0 (the sign, not 0) that satisfies the given equation. Give the answer in both radians and degrees. cos = sqrt( 2 )/

Question 402568: Find the acute angle that satisfies the given equation. Give 0 (the sign, not 0) that satisfies the given equation. Give the answer in both radians and degrees.
cos = sqrt( 2 )/2
Eh? I don't get what I'm supposed to do at all. :l Could anyone help? And clarify what I'm supposed to look for, and how - if possible, of course. :)
Thanks in advance.

Give the answer in both radians and degrees.
cos(theta) = sqrt( 2 )/2
---
theta = 45 degrees or pi/4 radians
