The angle lies in Quadrant II.
sin0=3/4
What is cos 0?

cosФ is  ⇒ B

Step-by-step explanation:

Let us solve the question using one of the identities of trigonometry

∵ sin²Ф + cos²Ф = 1

∵ sinФ =

→ Substitute it in the rule above to find cos Ф

∴ ()² + cosФ² = 1

∴ + cosФ² = 1

→ Subtract  from both sides

∴ cos²Ф =

→ Take √ for both sides

∴ cosФ = ±

∵ Angle Ф lies on the second quadrant

∴ cosФ is a negative value

∴ cosФ =  

∴ cosФ is

step-by-step explanation:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
