trigonometric subtraction.
it's been a long time since I've done this level of trigonometry and ii'm not sure this fits here but I really need help.

so i've been trying tos solve tan x - sin x = 150/205 + 1/(pi x 112)

been. going through all my old text books and formulas but keep going round in circles.

I doubt you would be able to solve these exactly. Use technology.
