Question 1181605
{{{cos(x)= 0.7660 }}}

{{{x=cos^-1( 0.7660 )}}}

{{{x=cos^-1( 0.7660 )}}}

{{{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+40=400}}}°, {{{760}}}°, {{{1120}}}°......


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