What is the value of sin(−θ) ?

Mathematics
1 answer:
Ghella [55]4 years ago
6 0

Answer:

A

Step-by-step explanation:

The cosine of a right triangle is the adjacent over the hypotenuse. If the cosine is -3/5 then it must be a right triangle with sides 3, 4, & 5 since this is a Pythagorean triple. This means the sin will be -4/5. We know its negative because the tangent is positive so this is the 3rd quadrant where both Sine and Cosine are negative.

JulijaS [17]

Answer:

24 scoops of iced tea

Step-by-step explanation:

Well, the way that I am going to solve this question is by calculating how many 1/4 cups she needs to get 1 cup and then multiply that by 6.

1/4 x 4 = 1

So 4 times 6 equals 24.

In conclusion, she needs 24 scoops

1/4 x 24 = 24/4. 24 divided by 4 equals the 6 cups Anna needs
