Given cosx= 0.7660 where 90°<_ x <_ 180, the first possible coterminal angle greater than x to the nearest degree is _____°
~~~~~~~~~~~~~~~~~~
The first sentence of the problem states
Given cosx= 0.7660 where 90°<_ x <_ 180.
This sentence is SELF-CONTRADICTORY, because an angle, satisfying the posed conditions, DOES NOT exist.
Therefore, the entire problem is a FAKE.
It is good to throw it to a GARBAGE BIN, O N L Y.
It can not be a subject of any solution --- so ignore the post by @MathLover1.
It makes no sense, exactly as the posted "problem" makes no sense, itself.
