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:







The answer is letter C which is 40/41. If you draw a triangle the sides found in the cos C is BC which is equal to 40 and the CA which is equal to 41 or the 40/41. It can not be the AB since it is in the opposite side of the cos C.
Answer:
looks like D but im not sure
Step-by-step explanation:
Look at the slope in each equation. For the first one is 15, the second is 25, the third is 40, and the fourth is 45.
Because the /-13/ should be positive so /-13/>/19/
