Answer:
A
Step-by-step explanation:
We are given that:
[tex]\tan(\theta)=1.3[/tex]
And we want to find:
[tex]\cot(90^\circ -\theta)[/tex]
Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:
[tex]\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)[/tex]
Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.
Our answer is A.
