最佳解答:
3tan(x + 30°) = 4 tan(x + 30°) = 4/3 x + 30° = 53.1° or x + 30° = 180° + 53.1° x = 23.1° or x = 203.1°
其他解答:
3tan(x+30°)=4 tan(x+30°)=4/3 (x+30°)=53.1° or 233.1° (x+30°)=53.1° x=23.1° (x+30°)= 233.1° x=203.1°

Solve the following equation for 0°≤x≤360°. (Give your answers correct to 1 decimal place if necessary.) 3tan(x+30°)=4最佳解答:
3tan(x + 30°) = 4 tan(x + 30°) = 4/3 x + 30° = 53.1° or x + 30° = 180° + 53.1° x = 23.1° or x = 203.1°
其他解答:
3tan(x+30°)=4 tan(x+30°)=4/3 (x+30°)=53.1° or 233.1° (x+30°)=53.1° x=23.1° (x+30°)= 233.1° x=203.1°
