The value of cos theta is 2/√29
Trigonometry identity
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
