We can solve this quadratic equation using factorisation method as follows

:x2−5x−36=0

x2+4x−9x−36=0

x(x+4)−9(x+4)=0

(x+4)×(x−9)=0

x+4=0orx−9=0

x=−4orx=9

Tan(x) = 2<br>solve for x.

lys-0071 [83]

Answer:

x = 63.43 , 243.43 degrees for 0 <x < 360.

Step-by-step explanation:

tan x = 2

The angle in the first quadrant whose tangent is 2 is x = 63.43 degrees.

If we consider the range 0 < x < 360 degrees tan x is positive in the third quadrant so x is also 180 + 63.43 = 243.43 degrees.
