Question

Use a calculator to find θ  to the nearest tenth of a degree, if    and ​  with θ  in QII ​

Quizplus · Accepted Answer

Use the inverse tangent function on both sides: 
tan(θ) = -4/-3
θ = tan^-1(-4/-3)
θ ≈ 126.5 degrees (rounded to the nearest tenth of a degree) 
This falls within QII, so the answer is C)126.5.
