You can use the CPCTC (Corresponding Parts of Congruent Triangles are Congruent) property. This means that when two triangles are congruent, all the corresponding parts are congruent to each other.

Have an awesome day! :)

If two triangles are congruent, then everything in the triangle be congruent. If one triangle has an angle of 50, how can the other triangle not have an angle of 50 and not be conguent. Thus if every part of a triangle is congruent, the every individual part is also congruent

Which set of numbers below DO NOT make a triangle? 0 7,7,7 O 6,3,3 0 3,4,5 O 5, 11,7

Hoochie [10]

Answer:

3,4,5

Step-by-step explanation:

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle therefore 3,4,5 is not triangle.

Hong purchased n notebooks. They were 5 dollars each. Write an equation to represent the total cost c that Hong paid.

klio [65]

Answer:

5n=c

Step-by-step explanation:

the equation 5n=c can represent the total cost Hong would have paid for the notebooks because given that each notebook costs $5, you would multiply 5 by the number of notebooks (n) that Hong would be purchasing, which would bring you to the cost (c) of the notebooks all together

sorry for the delay. hope this helps

Karen already owns 3 hair bands, and additional hair bands are priced at 8 for a dollar. How much money does Karen need to spend

kiruha [24]

Answer:

Karen needs to spend $4.5 to buy new hair bands.

Step-by-step explanation:

Given:

Hair bands Karen have = 3

cost of 8 hair bands = $1

Total Hair bands she require = 39

Hence Number of of new hair bands require = Total Hair bands she require - Hair bands Karen have = 39 -3 = 36

we need to find how much money she need to spend to buy new hair bands.

cost of 8 hair bands = $1

Cost of 36 hair bands = money need to spend on hair bands

By using Unitary method we get;

Money spend on new hair bands = $\frac{36}{8} = \$4.5$

Hence,Karen needs to spend $4.5 to buy new hair bands.
