( using degrees )
Use the inverse cot function:

I can look up the left side on my calculator

( x is less than 90 degrees. Hope this is what
they are looking for )

Answer by Natolino1983(23) (Show Source): You can put this solution on YOUR website!
First remember that cot(y) =cos(y)/sen(y), so y may be betweeen (0,90) or (180,270)
Arc cot (2,4) = 22,62 degrees or 202,62 degrees (first and thirds cuadrant)
2x + 25 =22,62 or 2x + 25 = 202,62 where x > =0 and x<=90
X =-1,19 or x =88,81 where x>=0 and x<=90
So solution is x=88,81 degrees.
Obs: calculator gives only 22,62. So the other one: 202,62 degrees is 180 + 22,62)
