Question 1201114
.
Solve for all values of 0, such that 0 deg < theta < 360 deg , rounding all values 
to the nearest tenth. If there is no solution, just press submit.
5tan(¤) + 7 = 0
~~~~~~~~~~~~~~~~~~~~


<pre>
    {{{5*tan(theta) + 7}}} = 0

    {{{5*tan(theta)}}} = -7

    {{{tan(theta)}}} = {{{-7/5}}}


In the interval [0°, 360°),  there are two approximate solutions

    {{{theta}}} = {{{arctan(-7/5)}}} + 180° = -54.7° + 180° = 125.3°

and

    {{{theta}}} = 125.3° + 180° = 305.3°.


<U>ANSWER</U>.  In the interval [0°, 360°),  there are two approximate solutions 125.3°  and  305.3°.

Solved.
