The sides of the right triangle are 7, 24, and 25.
It is important to know that the cosine function is equal to the ratio between the adjacent leg to Y and the hypothenuse.
[tex]\cos Y=\frac{7}{25}[/tex]
The sine function is equal to the ratio between the opposite leg to Y and the hypothenuse.
[tex]\sin Y=\frac{24}{25}[/tex]
The tangent function is the ratio between the opposite leg and the adjacent leg to Y.
[tex]\tan Y=\frac{24}{7}[/tex]
Hence, cosY = 7/25, tanY = 24/7, and sinY = 24/25.
