Aquadrilateral has vertices a(4,5), b(2,4), c(4,3), and d(6,4) which statement about the quadrilateral is true a abcd is a parallelogram with noncongruent adj sides b abcd is a trapezoid with only one pair of parallel sides c abcd is a rectangle with noncongruent adj sides d abcd is a square e abcd is a rhombus with non perpendicular adj sides

Let's find the lengths of all sides:

.

All sides are congruent, then this quadrilateral may occur to be square or rhombus. Check whether sides AB and AD are perpendicular. With this aim you should find vectors and :

,

.

The dot product: . This means that sides AB and AD are not perpendicular and quarilateral ABCD is not square.

correct choice is E.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
