The terminal side is which defines the angle when the angle is drawn in standard position.So, the other side is on the x-axis.

Then, you can draw a triangle with adjacent leg x = 12, opposite leg y = 5 and hypotenuse = sqrt (12^2 + 5^2 ) = 13.

So, the cosine of the angle is x-coordinate / hypotenuse = 12 / 13. That is option b. 12 / 13.

The cotangent, is the inverse of the tangent => cot = adjacent leg / opposite leg = x-coordinate / y-coordinate = 12/15. That is option c. 12/5.

The point (12, 5) is on the terminal side of angle θ. The value of cos θ is 12 / 13. The value of cot θ is 12/5.

Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.

In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slanted side is called the hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.

The point (12, 5) is on the terminal side of angle θ.

We can draw a triangle with adjacent leg x = 12,

opposite leg y = 5

hypotenuse = z

c= √(12^2 + 5^2 )

c = 13.

So, the cos = base / hypotenuse

The value of cos θ = 12 / 13.

Also, cot = adjacent leg / opposite leg

= x-coordinate / y-coordinate

= 12/15.

The value of cot θ = 12/5.
