Step-by-step explanation: it needs to add up to 180
4 x 5 x 5 is 100 if u distribute
Now 5 + 5 x 4 is 25
You have not provided the figures, therefore, I cannot provide an exact answer.
However, I can helps you with the steps.
One important thing to note is that when writing statements of congruency, the order of writing the letters is very important. This is because each side/angle in the first figure would be congruent to the corresponding side/angle in the second.
Therefore, all you have to do in the above question is write the congruent figures and determine the corresponding congruent sides/angles
Example:
If we are given that triangle ABC is congruent to triangle DEF
This means that:
AB = DE
BC = EF
AC = DF
angle A = angle D
angle B = angle E
angle C = angle F
Hope this helps :)
Answer: One vase should be placed 3 feet from the end of the mantel and the other vase should be placed 9 feet from the same end.
Step-by-step explanation:
You know that lenght of the mantel above their fireplace is 12 feet.
They want to place one vase 
of the distance from one end of the mantel. This distance in feet is:
They want to place the other vase 
of the distance from the same end of the mantel. Therefore, this distance in feet is:
Therefore, one vase should be placed 3 feet from the end of the mantel and the other vase should be placed 9 feet from the same end.
