What 3D figure/shape is it?
Answer:
![\sin\theta=-\frac{\sqrt{2}}{2}](https://tex.z-dn.net/?f=%5Csin%5Ctheta%3D-%5Cfrac%7B%5Csqrt%7B2%7D%7D%7B2%7D)
![\tan \theta = -1](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D%20-1)
The measure of the reference angle is ![45^{\circ}](https://tex.z-dn.net/?f=45%5E%7B%5Ccirc%7D)
Step-by-step explanation:
The reference angle of an angle is the magnitude of the smallest angle it makes with the x-axis. In this case, we have

Answer:
392 ft²
Step-by-step explanation:
Break this area into two parts, that is, into two trapezoids. The first trapezoid, on the left, has length 8 ft and average length (30 ft + 27 ft)/2, so its area is (8 ft)(28.5 ft) = 228 ft ².
The second trapezoid has width 8 ft and average length (19 + 22)/2 ft, or 8 ft by 20.5 ft). The area of this part is 164 ft².
Thus, the total area is 164 ft² + 228 ft², or 392 ft²
