Answer:
120 degrees
Step-by-step explanation:
This is a quadrilateral, and by definition, the sum of all the interior angles is 360. So, we can just sum up all the expressions and set them equal to 360:
2x + x + 2x + x = 360
Combine like terms and solve for x:
6x = 360
x = 360/6 = 60
<BCD = 2x = 2 * 60 = 120
Thus, the answer is 120 degrees.
Hope this helps!
X=1 so it is 1×1×1=1 so.... it is 19+1
Answer:
12 * 24 * 17 = 4896
10 * 12 * 4 = 480
4896 + 480 = 5376
the volume is 5376 cubic inches.
