For this case we have that by definition of trigonometric relations of a rectangular triangle, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. While the tangent of the same angle is given by the leg opposite the angle on the leg adjacent to the angle.
Then, according to the figure we have:

Answer:

I am gonna assume the answer is 8.If not another 4 i wish you could see the whole picture
If the sequence is like this, you actually don’t have to
formulate a formula. You just have to formulate a principle. You just have to
remember that when n is an odd number, the value would always be 1. If the n is
an even number, the value would always be 0.
Y = 2
slope = 0
hope it helps
