 Question 425192: If the terminal side of angle theta passes through the point (-4,3), what is the value of cos theta? A.) 3/5 B.) -3/5 C.) 4/5 D.) -4/5Answer by lwsshak3(6518)   (Show Source): You can put this solution on YOUR website!If the terminal side of angle theta passes through the point (-4,3), what is the value of cos theta? A.) 3/5 B.) -3/5 C.) 4/5 D.) -4/5 .. Given requirement gives us a right triangle in quadrant II where the the cos is negative and sin positive. This is also known as a 3-4-5 triangle with the hypotenuse=5 Therefore, cos of reference angle theta=-4/5 or ans D above
