<h3>Answer: Choice D.  12,600 feet</h3>

============================================================

Explanation:

We have two similar triangles here, so we can set up the proportion below to solve for x

5200/(5200+6500) = 5600/x

5200/11700 = 5600/x

5200x = 11700*5600 .... cross multiply

5200x = 65,520,000

x = (65,520,000)/(5200)

x = 12,600 which shows why the answer is choice D

side note: 12,600 ft = 2.386 miles approximately

Julia is designing a frame for a client. She wants to prove to her client that m∠AGE ≅ m∠FHD in her sketch. What is the missing
katen-ka-za [31]

The missing justification in Julia's angle proof is; Corresponding Angles Theorem

<h3>What is the angle theorem used?</h3>

We know that m∠AGE ≅ m∠HGB because they have congruent angles and are vertical angles.

Similarly, m∠HGB ≅ m∠CHE are alternate interior angles because two congruent angles on the inner side of the parallel lines are formed by a transversal.

In the diagram, m∠AGE ≅ m∠CHE would have to be corresponding Angles Theorem because parallel lines cut by a transversal would create congruent corresponding angles. That means a pair of angles on the same side of one of two lines that is cut by a transversal and on the same side of the transversal.

Answer:

A = 3 ft, B = 7 ft, C = 4 ft, D = 5 ft, Surface Area = 96 ft^2

Step-by-step explanation:

<u>Step 1:  Determine the sides</u>

A → 3 ft

B → 7 ft

C → 4 ft

D → 5 ft

<u>Step 2:  Determine the surface area</u>

Area of the sides

A= 4\ ft * 7\ ft = 28\ ft^2

A= 5\ ft * 7\ ft = 35\ ft^2

A= 3\ ft * 7\ ft = 21\ ft^2

Area of the top and bottom triangles

A= \frac{h\ *\ b}{2} = \frac{3\ ft\ *\ 4\ ft}{2} = \frac{12\ ft^2}{2} = 6\ ft^2 = 2(6\ ft^2) = 12\ ft^2

Total Area

28\ ft^2 + 35\ ft^2 + 21\ ft^2 + 12\ ft^2

96\ ft^2

Answer:  A = 3 ft, B = 7 ft, C = 4 ft, D = 5 ft, Surface Area = 96 ft^2
