Since it's a right triangle. then:

cosz = sin(90 - z) = sinp = 3/5

Answer:

[tex]cos(z)=\frac{3}{5}[/tex]

Step-by-step explanation:

we know that

In a right triangle

If [tex]\alpha+\beta=90\°[/tex] -------> complementary angles

then

[tex]cos(\alpha)=sin(\beta)[/tex]

In this problem

we have that

[tex]p+z=90\°[/tex] -------> complementary angles

so

[tex]cos(z)=sin(p)[/tex]

[tex]cos(z)=\frac{3}{5}[/tex]
