Trig 30
x/2 = 2pi/3 yields a unique solution of x = 4pi/3 Does this answer come from some trig equation? Your subject title suggests that. In that case find the period of the trig function, then add k(period) to 4pi/3, k an integer.

tan is a trig operator, it needs an operand. You probably mean something like tan^2 Ø - tanØ = 0 factor it tanØ(tanØ - 1) = 0 so tanØ=0 or tanØ=1 Ø = 0 or Ø = π/4 or Ø = 5π/4 since it asked for the positive acute angle Ø = π/4 radians or 45°
