Answer 1

Answer:

5. Since ∠CBD ≅ ∠CDB and ∠BAE ≅ ∠DEA, ΔABD and ΔBDE are equal. Therefore, the distances AD and EB are the same.

6. Since ∠EBC ≅ ∠ECB and AE ≅ DE, ΔABE and ΔCDE are equal. Therefore, the distances AB and DC are the same.

I hope this helps!

Answer 2

Answer:

Question 5

ΔCBD is isosceles as angles B and D are congruent

ΔCAE is also isosceles as angles A and E are congruent

CA ≅ CE as the triangle ΔCAE is isosceles

AB = AC - BC, ED = EC - DC ⇒ AB ≅ ED∠BAE ≅ ∠DEA - givenAE ≅ EA - reflexive propertyΔBAE ≅ ΔDEA - SAS congruency theorem

AD ≅ EB - corresponding parts of congruent triangles

Question 6∠EBC ≅ ECB ⇒ ΔECB is isosceles ⇒ EB ≅ ECAE ≅ DE - given∠AEB ≅ ∠DEC - vertical angles

ΔAEB ≅ ΔDEC - SAS congruency theorem

AB ≅ DC - corresponding parts of congruent triangles

Answer:

3) Reflexive Property

4) SAS

Step-by-step explanation:

ST ≅ TS

1. The Reflexive Property states that: a quantity is congruent (equal) to itself.

Example: a = a In this case, it could be seen as ST ≅ ST because they have/are the same side(s).RST ≅ UTS

1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.

Example: RST ≅ UTS (both have S and T) Can be seen as RST ≅ UST as well to make their similarity more evident.

2. Because it is given that RS ≅ UT and RT ≅ US, and it includes the same 2 lines being equal as given/said, RST ≅ UTS because of SAS (theorem).

Would y^10/y^10 become 1?

Answers

Answer:

yes

Step-by-step explanation:

If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y

If you are multipling the answer will be y^10 because 10 plus 10 is 20 and you keep the base which is y

Product = -14

Factors = 2 , (-7) because 2*(-7) = -14 and 2 + (-7) = -5

x² - 5x - 14 = 0

x² + 2x - 7x - 14 = 0

x(x + 2) -7(x + 2) = 0

(x + 2)(x - 7) =0

x + 2 = 0 ; x -7 =0

When using a pronoun to refer to a person, speakers must either specify a gender or say something like "he or she." Not only can this be cumbersome, but it means that there is no good pronoun choice when a person's gender is unknown to the speaker. Sweden addressed this problem in 2015 by adding a new pronounhenwhich refers to a person without specifying a male or female gender. Hen does not replace the Swedish pronouns han, meaning "he," or hon, meaning "she"; it simply adds another option.
