cos%28x%29=+0.7660+
x=cos%5E-1%28+0.7660+%29
x=cos%5E-1%28+0.7660+%29
x=0.698201...(result in radians)
x=40°
coterminal angles is as simple as adding or subtracting 360° or 2pi to each angle
Positive coterminal angles greater than x: 360%2B40=400°, 760°, 1120°......

the first possible coterminal angle greater than x to the nearest degree is 400°.

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.
