which postulate or theorem, if any,could be used to prove the triangles congruent? if not enough information is given, write not
Rus_ich [418]
The ways we can prove the triangles congruent:

SAS (side, angle, side)
ASA (angle, side, angle)
AAS (angle, angle, side) 
SSS (all sides equal)
RHS/HL (Right Angle-Hypotenuse-Side/Hypotenuse-legs)

In these cases:
A. <B = <E
<A = <D
AC=DF

AAS (angle, angle, side) could be used.

B. AB=ED
BC=EF
AC=DF

SSS (all sides equal) could be used.

C.<BEA=<CED (right opposite angles)

As there is only one pair of equal angles we can find,there is not enough information.

D.<B = <E
BC=CE
<ECD < ACE(right opposite angles)

ASA (angle, side, angle) could be used.

Hope it helps!

Answer:

Step-by-step explanation:

Write a system of equations to model the situation. Add the equations to eliminate the y-term and then solve for x. Substitute the value for x into one of the original equations to find y. Check your answer by substituting x = 8 and y = 2 into the original system.

62.54 ÷ 0.025? <br><br>can't figure it out :/​
scZoUnD [109]
Answer:

Step-by-step explanation:

Well first you have to see how many times 0.025 goes into 62.54. You can find that out by multiplying 0.025 by a number you will think is equal to 62.54. Then if the answer is too big try to decrease the number you multiplied it with. If its too small try to increase the number you multiplied it with.
