In the unit circle shown in the figure, points A, B, C, D, and E correspond to the angles o, and respectively. The coordinates of the
points are shown in the figure.
You have learned that for any point (x, y) on the unit circle that corresponds to an angle 8, sin 8 = y and cos 0 = x. Using the unit circle, find the
values of all six trigonometric functions for the five angles and complete the table.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

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".

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
