Find all angles 𝜃 between 0° and 180° satisfying the given equation. Round your answer to one decimal place. 

tan(𝜃) = 9

 

Im cant figure out how to solve these types of problems.

Only in Q I   nad Q III   is tangent a positive number      ( remember tan = sin/cos) 

    since the question asks for Φ between  0 and 180 degrees, you only get one answer in Q I

        using a calculator         arctan (9) = 83.7 degrees
