The value of cos theta is 2/√29
<h3>Trigonometry identity</h3>
A trigonometry identity are expressions expressed as cosine, tangent, sine.
Given the following trigonometry identity
cot theta = 2/5
1/tan theta = 2/5
tan theta = 5/2
Determine the hypotenuse
hyp² =5^2 + 2^2
hyp² = 25 + 4
hyp = √29
Determine the value of cos theta
cos theta= adj/hyp
cos theta= 2/√29
Hence the value of cos theta is 2/√29

Answer:
3 out of 10
Step-by-step explanation:
First convert 3 1/5 into an improper fraction.
We do that by multiplying the denominator to the whole number and adding it to the numerator and we keep the denominator.
5 * 3 + 1 = 16
So 3 1/5 is equal to 16/5
16/5 * 5/8
Multiply the numerators together and the denominators together:
16/5 * 5/8 = 80/40 = 2
So the product of 3 1/5 and 5/8 is 2.
