Easy math i will pick the brainliest i need this fast

1. CA ⊥ AB

2. AB = AB'

3. CA = CA

4.  ∠CAB ≅ ∠CAB'

5. SAS

Step-by-step explanation:

1. The crowbar is perpendicular because it intersects

2. It is a 180 degree rotation

3. CA = CA is the same line so they will be equal due to the reflexive property that states which means it is equal to itself

4. They are congruent because being adjacent which is two angles that have a common vertex and a common side and they are pendicular because it has a horizontal and vertical lines

5. Side Angle Side, we talk about two sides and an angle which is included in the two congruent sides.

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!
