So
C=10
3c+c/2c means
3(10)+10/2(10)
30+10/20
40/20=2
Let C represent the number of cookies shared.
Let 5 represent Sarah and her 4 friends.
C = 5 * 3
C = 15
So, since 5 friends got 3 cookies each, the total number of cookies shared is 15.
The equation will be: C = 5 * 3 or C = 5(3)

By using trigonometric relations, we will find that:
sin(θ) = (√33)/7 = √(33/49)
<h3>How to find the value of the sine?</h3>
Remember that for a right triangle, we have the relations:
cos(a) = (adjacent cathetus)/(hypotenuse)
sin(a) = (opposite cathetus)/(hypotenuse).
Here we know that:
cos(θ) = 4/7
Then we can say that we have a triangle with an adjacent cathetus of 4 units and a hypotenuse of 7 units. Now we need to find the other cathetus.
opposite cathetus = √(7^2 - 4^2) = √33
Then we can write:
sin(θ) = (√33)/7 = √(33/49)
