Answer:
See the highlighted values below.
Step-by-step explanation:
The following right angled triangle will have an angle whose cosine is 5/13.
Hypotenuse = 13 and the 2 legs will be 5 and 12 units long. The 12 is found using the Pythagoras theorem ( 13^2 = 5^2 + 12^2).
cos O = adjacent / hypotenuse = 5/13.
So sin O = opposite / hypotenuse = 12/13.
tan O = opposite / adjacent = 12/5.
csc O = 1 / sin O = 13/12.
sec O = 1 /cos O = 13/5.
cot O = 1 / tan O = 5/12.
