Question

Answer the question using the given information. In the space provided, type the answer without any spaces between the letters, numbers, or symbols.

sin θ

   

cos θ = - 45, tan θ < 0

Answer 1

Must be a typo somewhere

"cos(theta) = -45" is impossible, as -1 < cos(theta) > 1

so, odds are you meant to type theta=-45 degrees, which is quadrant IV where cosines >0 and sines<0 and tangents <0

then cos(theta) = (1/2)sqr2 = about 1.414/2 = 0.707

and sin(theta) = -(1/2)sqr2 = about -0.707
