Area of trapezoid = (1/2) (b1 + b2) h
= (1/2) x (12 + 24) x 6 sqrt 3
= 108 sqrt 3
area of Hexagon = 2 x Area of trapezoid
= 2 x 108 sqrt 3
= 216 sqrt 3
Answer:
x = 7
Step-by-step explanation:
Remember that the axis of symmetry (a vertical line that passes through the vertex) is exactly halfway between the two x-intercepts. Thus, the x-coordinate of the vertex is 7.
Now, we know that 90°< θ <180°, that simply means the angle θ is in the II quadrant, where sine is positive and cosine is negative.
