The ratio of cos Z is cos Z = 3 / 5
<h3>How to find the trigonometric ratios of a right triangle?</h3>
A right triangle has one angle of the triangle as 90 degrees.
The sides of the right triangle can be found using trigonometric ratios.
Therefore,
sin ∅ = opposite / hypotenuse
sin Z = 3 / 5
Using Pythagoras theorem,
c² = a² + b²
5² - 3² = b²
b² = 25 - 9
b² = 16
b = √16
b = 4
Hence,
P + A = 90 degrees (complementary angles)
Therefore,
sin P = cos Z
cos Z = 3 / 5
