Multiple Choice

θ is an acute angle and sin θ and cos θ are given. Use identities to find the indicated value.
- $\sin \theta = - \frac { \sqrt { 5 } } { 3 } , \cos \theta = \frac { 2 } { 3 }$ . Find $\cot \theta$

A) $\frac { - 2 \sqrt { 5 } } { 5 }$
B) $\frac { - 3 \sqrt { 5 } } { 5 }$
C) $\frac { 3 } { 2 }$
D) $\frac { \sqrt { 5 } } { 2 }$ θ is an acute angle and sin θ is given. Use the Pythagorean identity sin2 θ + cos2 θ = 1 to find cos θ.
