Question

3cot(2θ)+3=0 Can you help me solve this in degrees. Rounded to the nearest whole degree

Answer 1

3 cot (2θ) + 3 = 0

Take 3 to the other side

3 cot (2θ) = -3

Divide both sides by 3

cot (2θ) = -3/3

cot (2θ) = -1

But cot = 1/ tan

1/ tan (2θ) = -1

Assume x = (2θ)

Then;

tan^-1 {-1 } = 2θ

-45 ° = 2θ

-22.5° = θ

-23° =θ

Answer

θ = -23°
