Hi there!
For congruent triangles, all angle measures and sides are congruent. So, if you look at the other triangle, and find the corresponding side, it will be the same measure.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
We are given a compound known to be Sodium Bromine (NaBr). This compound has a molecular weight of
Na=23 g/mol and Br=80 g/mol
NaBr=23+80= 103 g/mol
Assuming if we have 1 mol of NaBr, then we have 80 g of Bromine (Br). Calculating its percent composition in the total NaBr compound, we get
%Br= (80/103)*100=77.7%
Therefore, the answer to the question above is letter A.

Step-by-step explanation:
What is the length of the apothem, rounded to the nearest inch? recall that in a regular hexagon, the length of the radius is equal to the length of each side of the hexagon. 4 in. 5 in. 9 in. 11 in.
The flow rate is 2 quarts per minute. There are 4 quarts in a US gallon, so 2 quarts divide 4 quarts per US gallon = 0.5 gallons per minute There are 60 seconds in a minute, so the flow rate is 0.5 gallons per minute divide 60 seconds per minute = 0.0083 gallons per second
