Question

the values of sin theta1,cos2 thera2 and tan theta3 are given as 1/2,-1/2 and 3 (not in order), for some angles theta1, theta2,and theta3 option1.The value of tan theta3 could be -1/2.option2. The value of sin theta3 can not be zero option3.the value of cos2 theta can't be -1/2 option4.the value of cos2 theta2 can't be3.choose incorrect statement. plz don't spam and give the correct answer. I will mark brainliast​

Answer 1

Since sinθ=-12⇒θ =210∘ or 330∘ and tanθ=1√3⇒0=30∘ or 210∘ Hence, θ=210∘ or 7π6 is the value
