Answer:
The quadrilateral is a trapezoid
The angles are complementary.
This means they add to 90 degrees.
(2x + 1) + (x + 5) = 90.
3x + 6 = 90. (Combine like terms)
3x = 84. (Subtract 6 from each side)
x = 28. (Divide 3 from each side)
x = 28
D is correct
Answer:
s cubed
Step-by-step explanation:
Formula for volume of a cube is side ^3
Answer:
No, they are co-planar.
Step-by-step explanation:
Points Q, R, X, and W are all in the plane QRXW. Planes do not have to be at ninety-degree angles (that is, straight up and down or straight to the left and right). However, the points Q, S, U, and X would not be coplanar as a plane must be a flat surface.
