The equation for ΔFON is sin F = 9/18.
Hence, option B) sin F = 9/18 is the correct answer.
This question is incomplete, the complete question is;
Which equation is correct for ∆FON?
Answers:
A.) cos F= 9/18
B.) sin F 9/18
C.) sin F=18/9
D.) cos F=18/9
Which equation is correct for ΔFON?
From the diagram, we have a right angle triangle.
- Hypotenuse = 18
- Perpendicular height or opposite to ∠F = 9
- Equation of angle F = ?
Note that; sinθ = Opposite / Hypotenuse
Therefore, for angle F
sin F = Opposite / Hypotenuse
sin F = 9/18
The equation for ΔFON is sin F = 9/18.
Hence, option B) sin F = 9/18 is the correct answer.
