Answer:
Given : EFGH is a parallelogram.
Prove: EG bisects HF and HF bisects EG.
Since, a parallelogram has two pairs of congruent and parallel sides.
Therefore, In parallelogram EFGH,
EF≅GH and EH≅FG
Also, EF║GH and EH║FG
Since,In triangles EKF and GKH,
EF≅HG
Since, EF║HG
⇒∠FEK ≅ ∠HGK and ∠EFK ≅ ∠ GHK ( When two parallel lines are cut by a transversal alternative interior angles are congruent )
⇒ Δ EKF ≅ Δ GKH ( ASA congruence postulate )
⇒ EK ≅ GK and FK ≅ HK ( CPCTC)
⇒ EG bisects HF and HF bisects EG ( Definition of bisector)
Hence proved.
Find the missing side of the right triangle using Pythagorean Theorem:
10^2 =8.7^2 +x^2;
x^2=100-75.69=24.31
x= sqrt 24.31~ 4.93
Area of trapezoid is area of triangle+area of a rectangle.
A=(8.7x4.93/2)+(12x4.93)
A=80.6055 ~81 ft^2

Answer:
A. 13 boxes
B. $18.00
C. $3.60
D. 0.30
Step-by-step explanation:
6 boxes = 21.60
that is 3.60 per box
A. 50.00/3.60 = 13.88 so he can purchase 13 boxes
B. 1 box is 12 ounces
60/12 = 5 boxes needed for 60 ounces. 5 x 3.60 = 18
C. One box is 3.60
D. 3.60/12 = 0.30 per ounce
