Cosine stands for "complementary sine." The sine of an angle is the cosine of the complementary angle and vice versa. Complementary angles add to 90°.

Answer: sin(B) = cos(90 - B)

It's true for any angle, and it doesn't have much particularly to do with a triangle.

(Solving Equations) Ken has $20.00. Coffee costs $4.79 per pound. Which equation will calculate the number of pounds of coffee,

aev [14]

Answer: A. 4.79(n)=20.00

Step-by-step explanation:

we need to find what amount of coffee (per pound) is equivalent to $20.00

so we take the unknown amount (n) and multiply it by $4.79

for example, say Ken wants 4 pounds, we need to know if it is equivalent to $20.00

so take 4.79 and multiply it by 4 to see if it is equal to or less than $20.00 in this case $4.79 x 4 = $19.16

hope this helps (^_^)
