If sin⁡ θ=−4/5, and 270° < θ < 360°what is cos θ?

cosΘ =

Step-by-step explanation:

Using the trigonometric identity

sin² x + cos²x = 1

⇒ cosx = ±

Since 270 < Θ < 360 then cosΘ > 0

cosΘ =

         =

         = =

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

answer:

your answer is: c. 196 7/8 in^3.
