Using the addition rule of the Sine function and the Cosine function, we obtain .
<h3>What are the formulas for (sin x + sin y) and (cos x + cos y)?</h3>
- The formula for the addition of two Sine functions () is .
- The formula for the addition of two Cosine functions () is .
Given that
Then using the above formulas, we get:
(1)
(2)
Dividing the equation (1) by (2), we get:
(3)
Now, we know that .
Thus, using the above formula, we get from (3):
Therefore, using the addition rule of the Sine function and the Cosine function, we obtain .

Answer:
i think it is the second one y=35x
Step-by-step explanation:
when we put for example 2 in place of x it will be
it will y=35*2
y=70 so i believe it is the second one
i am soo sorry if it was wrong
Answer:
8(p) +4 =10(p) , P = 2
Step-by-step explanation:
The equation that could be found as given in the question that,
$8 per pizza (p) with a $4 delivery fee which is equal to $10 pizza (p) without any charges.
8(p) +4 =10(p)
Rearranging the equation to find the number of pizza (p)
4 = 10p - 8p
4 = 2P
4/2 =P
2 = P
P = 2
Therefore, there are 2 pizzas for $8 of pizza with delivery fee and 2 pizzas for $10 without any charges.
Answer:
The value of x is 5.
Step-by-step explanation:
Label the diagram such as
Given:
AD= x
DB= x +5
AE = x - 2
EC = x + 1
DE || BC
To Find:
x = ?
Solution:
Basic Proportionality Theorem:
"If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio".
DE || BC
∴ ...Basic Proportionality Theorem
Substituting the values in it we get
The value of x is 5.
