This page contains Question 22 out of 27. Question 22: (1 point) If tan 0 3, then tan -0 O none of these Remaining time: Unlimite

Solution

tan theta=3

tan(pi/2 - theta) = cot theta

cot theta = 1/tan theta =1/3

Question no 21

sin²theta+2=2cos theta

cos²theta+2cos theta-3=0

(cos theta-3)(cos theta+1)=0

cos theta=3,cos theta=-1

theta=180degree
