7sin^2theeta+3cos^2theeta=4
7sin^2theeta+3(1-sin^2theeta)=4
7sin^2theeta+3-3sin^2theeta=4
4sin^2theeta=1
sin^2theeta=1/4
sin theeta=1/2
theeta=30°
now
tan theeta = tan30°=1/√3
7sin^2theeta+3(1-sin^2theeta)=4
7sin^2theeta+3-3sin^2theeta=4
4sin^2theeta=1
sin^2theeta=1/4
sin theeta=1/2
theeta=30°
now
tan theeta = tan30°=1/√3
