Can someone tell me the difference between sine, cosine, and tangent

sin∅ = opposite over hypotenuse

cos∅ = adjacent over hypotenuse

tan∅ = opposite over adjacent

Step-by-step explanation:

Each of these trigs are used to find angles or lengths of a triangle.

sin∅ would be the y-value of the unit circle.

cos∅ would be the x-value of the unit circle.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
