Answer: a. proportional side lengths.


Step-by-step explanation:

In the given figure we can see in ΔABC  and  ΔDEF

∠A=∠D=53°

∠B=∠E=37°

∠C=∠F=90° [right angles]

So by AAA similarity criteria they are similar.

We know that the side lengths of similar triangles are proportional, thus A is correct.

We can see from the figure that all the corresponding sides are proportional but not of same measure.Therefore, they are not congruent and not same.

Only A is the correct option.

Look at the sizes, can ABC be multiplied to a number where it would be the exact size as DEF? If so, check both proportional side lengths and both being congruent. However, since ABC is smaller than DEF, do not check them being the same size or being congruent, as them being congruent would mean that their sides are equal in length to each other.

Raymond bought a used truck for $16,948. If the sales tax in his states is 11 percent, what was the final price for his car.
BabaBlast [244]
Hi there! To find the total price for Ray's car, multiply the price of the car by 111% (1.11), because that will take us straight to finding the total price of the car. 16,948 * 111% (1.11) is 18,812.28. There. The total price for Ray's car is $18,812.28.

Tom has 2 8-foot long boards he needs to cut pieces that are 15 inches long. How many 15 inch pieces can he cut from the two boa
Ksju [112]

Answer:

Tom can cut 12 (15 inch pieces) from the two boards.

Step-by-step explanation:

We're first given foot measurements and we're asked to find the answer in inches. That means we must convert 8 feet to inches, which is a 1:12 inches conversion. 8 times 12 will give you 96, so now you will multiply that value by 2 because Tom has 2 8-foot long boards. That will give you 192 inches. Since the question is asking for 'how many 15 inch pieces he can cut from the two boards?', you will need to divide 192 inches by 15 to find the answer. This will give you 12.8 boards. Because you can't have parts of an object, the answer will be 12 whole boards.

The length of a rectangular board is 10 cm longer than its width. The width of the board is 26 cm. The board is cut into 9 equal
kvasek [131]
Each piece will be 26cm by 4cm.

Width is 26 cm.
Length is 36 cm. The problem states that the length is 10 cm longer than the width. Since width is 26 I just added 10 to arrive at 36 cm.

36 / 9 = 4 cm.

The width will still be 26 but the length is now 4 cm. 

Area = length * width
Area = 4 * 26
Area = 104 cm
