If m∠ABC = 53° and m∠ECD = 40°, which statement explains whether the AA similarity postulate can be used to determine whether ΔBAC ~ ΔEDC? Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.

Yes, the AA similarity postulate can be used because a reflection over line f will establish that ≅ .

No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.

No, the AA similarity postulate cannot be used because a reflection over line f will establish that and are not congruent.

C. No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.

Step-by-step explanation:

i took the test :)

Also, if you know that the triangles inner angles have to equal 180 degrees, and you do the math (40+53)= 93. And we already know that the missing is 90 degrees to 93 +90= 183, which is not possible. SO, a and b are eliminated. Then it is asking by AA similarity and that deals with angles and choice d deals with sides and c deals with angles, so that means that the only correct answer is c.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
