Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

1. Get total leakage

40psi - 33psi = 7psi

7psi for 7days. Divide total leakage with number of days to get the rate per day.

7psi/ 7days = 1psi/day

Answer:
10=2x+y

Explanation:
Let x be equal to the first number.
Let y be equal to the second number.

The question tells us that 10 is equal to double the first number plus the second number.

We can translate this information into an equation by looking at key words and translating them into math.

Key words:
equal: =
double: *2
plus: +

Using this, we get the equation 10=2x+y.
