Answer:
the angle is 40°
Step-by-step explanation:
180 - 140 = 40
The formula for the area of a trapezoid is Area = (top + bottom)/2 x height
Using the given information we can solve for x:
234 = (20+32)/2 * X
234 = 52/2 * X
234 = 26 * X
X = 234/ 26
X = 9 units.
The answer is B.
Plane CBD because it contains both points
(9+x)÷2 =3 , x= 6-9 so, x = -3
(0+y)÷2 =8 , y=16
B ( -3 ; 16 )
