<u>Given</u>:
The triangle ABC is a right triangle.
The length of AC = 25, the length of AB = 7 and the length of BC = 24
We need to determine the ratios of sin C, cos C and tan C.
<u>Ratio of sin C:</u>
Using the trigonometric ratio, the ratio of sin C is given by

where
and 
Thus, we get;

Substituting the values, we get;

Thus, the ratio of sin C is 
<u>Ratio of cos C:</u>
The ratio of cos C can be determined using the trigonometric ratio.
Thus, we have;

where
and 

Substituting the values, we get;

Thus, the ratio of cos C is 
<u>Ratio of tan C:</u>
The ratio of tan C can be determined using the trigonometric ratio.
Thus, we have;

where
and 
Thus, we have;

Substituting the values, we get;

Thus, the ratio of tan C is
