Anna007 [38]

Answer: D: Corresponding parts of congruent triangles are congruent


Step-by-step explanation:

If two triangle are congruent using postulate of theorems of congruence then their corresponding parts are congruent by CPCTC rule.

The CPCTC rule says that if two triangles are congruent then their each corresponding part whether angles or sides must be equal.

Here if triangle abc= def by side-side-side triangle congruence theorem,

then b=e [which is a corresponding part of both triangles] by Corresponding parts of congruent triangles are congruent.

If its going by $11 for 2 hours then he babysat ?


ok so $11= 2 hours


11 x 3= 33    half of eleven is 5.5


so 33+ 5.5 = $38.50 so I believe the answer is 6 hours and 30 min but I'm not 100 percent positive

Can u plzz help me with my homework
schepotkina [342]
The unit rate for Hakim's car is traveling 30 feet per second (I just simplified 600/20). Then the unit rate for Andre's motorcycle would be 25 feet per second (I simplified 300/12). So in conclusion, Hakim's car is traveling faster. So then, 30 > 25.

The length of two sides of a triangle are 10, 15 find the range of possible lengths for the third side
Zepler [3.9K]

Answer:

Range for third side is  

( 5 , 25 )  cm.

Step-by-step explanation:

As two sides of triangle are  10  and  15 ,

the third side would have to be less than the sum of other two sides i.e. less than  25  cm.

On the other hand if it is smaller one than this side plus side of length  10

should be greater than  15  and therefore

this side is greater than  15 − 10 = 5  cm.

Hence range is  

( 5 , 25 )

Hope this answer helps you :)

Have a great day
