Question

Use the Pythagorean Theorem to find the length of the missing side. Then find the indicated trigonometric function of the given angle. Give an exact answer with a rational denominator.

Answer 1

We will have:

`h=\sqrt[]{7^2+6^2}\Rightarrow h=\sqrt[]{85}`

We will have then the the secant of theta will be:

`\sec (\theta)=\frac{\sqrt[]{85}}{7}`

So the answer is C.
