Answer:

cos theta = -0.278

sin theta = -0.961

Explanation:

Given the expression

tan theta = 3.454

Get the value of thets

theta = arctan 3.454

theta = 73.85degrees

since theta is between 90 and 270 and lies in the third quadrant, then;

theta = 180+73.85

Get cos theta and sin theta

cos theta

= cos 253.85

= -0.278

sin theta

= sin 253.85

= -0.961

Hence cos theta and sin theta are -0.278 and -0.961 respectively
