Answer:





Step-by-step explanation:
Given that:
is an angle in a right angled triangle.
and 
To find:
To draw the triangle and write other five trigonometric functions in terms of C.
Solution:
We know that cosine of an angle is given by the formula:

Here, we are given that
OR

i.e. Base = C and Hypotenuse of triangle = 1
Please refer to the right angled triangle as per given statements.
, with base PR = C units
and hypotenuse, QP = 1 unit
is the right angle.
Let us use pythagorean theorem to find the value of perpendicular.
According to pythagorean theorem:
