Step-by-step explanation:

Answer with explanation:

Given:  △ABC is an isosceles triangle with legs AB and AC.Also, △A Y X is also an isosceles triangle with legs A Y and AX.

To Prove: △ABC ~ △A Y X

Proof with Statement

1. △ABC is isosceles with legs AB and AC; △A Y X is also isosceles with legs A Y and AX.

2.AB ≅ AC and A Y ≅ AX.→definition of isosceles triangle

3.AB = AC and A Y = AX →→ definition of Congruency.

4.→→A Y × AC=AX × AC⇒[Multiplication property of equality]

5.≡A Y × AC=AX × AB⇒[Substitution property of equality]

----------------[Division property of equality]

7.Also, ∠A is common angle between two triangles.That is,

 ∠A=∠A------------[Reflexive property]

⇒Missing statement and Reason in the entire proof.

8.△ABC ~ △AYX----[SAS]

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
