A right triangle has side lengths 7,24, and 25 as shown below.

Using the principle of trigonometry, the values of CosB, TanB and SinB are 7/25, 24/7 and 24/25 respectively
Recall from trigonometry :
Cos B :
Cos B = Adjacent / hypotenus
Cos B = 7/25
Tan B :
Tan B = opposite / Adjacent
Tan B = 24/7
Sin B :
Sin B = opposite / hypotenus
Sin B = 24/25
Therefore, the values of the Cos, Tan and Sin of the angle B are 7/25, 24/7 and 24/25 respectively.
