2Tanx-2=0 Help please

Question

I dont understand it I cant find it on the unit circle

Answer 1

2*tan(x)-2=0

2*tan(x)=2

tan(x)=1

so find invers tan(1)

evreewon shood no tan(45 deg)=1

Answer 2

OR U CAN TRY T N THS WAY Given.....2tanx -2 =0 > tanx -1 =0……… tan^2x - 1=0……… sin^2x -cos^x =0 > …-cos 2x = 0 . . > cos 2x = 0 2x = cos^-1(0) 2x = 90 , 270.………… x = 45 , 135
