Using the Law of Sines, which ratio can help you correctly find the value of angle A ?
sin A15=sin 85°40
Start Fraction sine upper A over 15 End Fraction equals Start Fraction sine 85 degrees over 40 End Fraction
sin A15=sin 85°10
Start Fraction sine upper A over 15 End Fraction equals Start Fraction sine 85 degrees over 10 End Fraction
sin A10=sin 85°15
Start Fraction sine upper A over 10 End Fraction equals Start Fraction sine 85 degrees over 15 End Fraction
sin A15=sin 40°10
Start Fraction sine upper A over 15 End Fraction equals Start Fraction sine 40 degrees over 10 End Fraction
The correct ratio that can help you find the value of angle A is:
sin A15=sin 85°40
(Start Fraction sine upper A over 15 End Fraction) equals (Start Fraction sine 85 degrees over 40 End Fraction)
