PLEASE HELP WILL MARK AS BRAINLIEST The base of a ladder is 10 feet away from a vertical building. The ladder top rests at the top of the building. The ladder's angle of elevation from the bottom of the ladder to the top of the building is 70 degrees.
What is the height of the building?
A. 27.47 ft.
B. 41.76 ft.
C. 53.30 ft.
D. 13.94 ft.
E. 32.14 ft.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
