In a unit circle, the sine of the angle is represented by the vertical leg of the triangle. what is represented by the horizontal leg of the triangle? a. cosecant of the angle c. cosine of the angle b. tangent of the angle d. cotangent of the angle

Option c

Step-by-step explanation:

A unit circle is one which has centre at the origin and radiu 1.

Consider a vertical line from a point on the circle.

The vertical line along with x axis and the line joining point and origin will form a right triangle

sine of the angle = opposite/hypotenuse = vertical leg/1 = vertical leg

Similarly we have

adjacent / hypotenuse = horizontal leg/1 = horizontal leg = cosine of the angle

Hence option c is right
