Answer:
cost of pizza I 5 and using proper cleaning
the value of sin ∅ is 12/ 13
<h3>Quadrants and the "cast" Rule:</h3>
- In the first quadrant, the values for sin, cos, and tan are positive.
- In the second quadrant, the values for sin are positive only.
- In the third quadrant, the values for tan are positive only.
- In the fourth quadrant, the values for cos are positive only.
From the given question,
We have, cos ∅= 5/13
From the trigonometric identities, we have that
Then , let's substitute the value of cos ∅
Let make sin the subject of formula and find the squares of the fraction
sin²∅ =
Find the LCM
sin²∅ =
Find the difference
sin²∅ =
Find the square root
sin∅ =
sin∅ =
In quadrant II , sin is positive, so we have
sin ∅ = 12/ 13
Thus, the value of sin ∅ is 12/ 13

3y×(2y+5)
Multiply each term in the parentheses by 3y
3y×2y+3y×5
Calculate the product
6y²+3y×5
Now we do the same thing only different way
3y×2y
Multiply the numbers
6y×y
If a term doesn't have an exponent , it is considered that the exponent is 1
6y^1×y^1
Multiply the terms with the same base by adding their exponents
6y^1+1
add the numbers
6y²
6y^2+3y×5×
calculate the product
6y²+15y
It's the same thing only different way ok
3y×5
Multiply the numbers
15y
answer: 6y²+15y
