In the given triangle for angle A, the values of the base, hypotenuse, and height are
Base = B = 36
Height = Perpendicular = P = 48
and Hypotenuse = H = 60
The trigonometric functions are given as
[tex]\begin{gathered} sin\text{ A = }\frac{perpendicular}{hypotenuse}=\frac{P}{H} \\ cosA=\frac{base}{hypotenuse}=\frac{B}{H} \end{gathered}[/tex]
On putting the values we have
[tex]\begin{gathered} sinA=\frac{48}{60}=\frac{4}{5} \\ cosA=\frac{36}{60}=\frac{3}{5} \end{gathered}[/tex]
Hence, the values of cosA and sinA are 3/5 and 4/5.
