Assume that $ \theta $ is an acute angle in a right triangle satisfying the given conditions. Evaluate the indicated trigonometric
function.
-$$\cos \theta = \frac { 10 } { 11 } ; \sec \theta$$
A) $\frac { \sqrt { 21 } } { 10 }$
B) $\frac { \sqrt { 21 } } { 11 }$
C) $\frac { 10 } { \sqrt { 21 } }$
D) $\frac { 11 } { 10 }$

The secant function is the reciprocal of the cosine function, so $\sec \theta = \frac{1}{\cos \theta} = \frac{1}{\frac{10}{11}} = \frac{11}{10}$.
